Dog barking in the snow


Dogs bark to communicate their emotions. Different barks can mean different things and variations in bark sounds are also caused by individual characteristics. A Great Dane's bark sounds somewhat different to that of a Chihuahua even when they mean the same thing. All dogs bark at some time but if your dog is a persistent barker you should seek professional assistance before it becomes a nuisance to other people.

Dog training

Basic training for dogs

A dog owner is responsible for their pet in public places, so if your dog misbehaves you could be in trouble. A poorly trained dog can also be a danger to itself. Imagine the consequences if your dog ignores you and runs across a busy road. In order to have the perfect pet you will need to start training when your dog is very young. The rewards of this are clear – there is perhaps no greater pleasure than owning a well-behaved dog.

Destructiveness and chewing

Having a young puppy in the house brings much pleasure but puppies also bring with them many undesirable behaviours. Early training is important to ensure that your puppy grows up understanding the rules in your house and fits in with your lifestyle. All dogs chew at some point in their life and this is only recognised as problem behaviour when chewing affects objects you would rather weren't chewed!

Firework display

Firework fear

Firework fear is a common problem in dogs. It is not surprising that animals are scared of fireworks since they are very loud (up to 150 decibels). Sounds this loud can be physically painful as well as inducing fear. The noise from fireworks also lacks a clear pattern, with the source of the noise not identifiable and sounds occurring in short repeated bursts. The unpredictable nature of the sounds can make even normal animals react fearfully. Animals may become more sensitive with repeated exposures to the noise. In some animals a true phobia exists and these animals cannot get worse with time since they are always fully reactive to the noise.

House training your puppy

House training is the term we normally use for the process of training a puppy to go outside to urinate or defaecate (toilet) rather than toileting in the home. Once puppies have been house trained they should remain clean in the house throughout their life. If your dog has been house trained and then starts to mess in the house again you should consult your veterinary surgeon. A loss of toilet control can be caused by health problems and emotional disorders such as anxiety or fear.

Dog chewing fabric


Dogs sometimes eat things that are not food. Pica is defined as the persistent chewing and consumption of non-nutritional substances that provide no physical benefit to the animal. It can be a sign of distress or anxiety. There are many potential causes of this anxiety including changes in the social or physical environment or because of an internal oddness in how the animal perceives or interacts with the world.

Eating objects, such as rocks, can also be very dangerous for your dog, as these can be stuck in the stomach or intestine. Sharp objects, such as sticks, can cause damage to the delicate lining of the intestinal tract. It is therefore important that you know more about this behaviour to understand how to manage it appropriately.

Separation anxiety

We ask a lot from our dogs when we expect them to fit into our hectic modern lives. Happily most dogs adapt to our lifestyle with ease but there are a few dogs out there for whom the modern way of life can get a bit too stressful at times. Some of these dogs turn to destruction as a way of releasing their feelings. Living with these dogs can be very stressful for owners.

Cystitis (bladder inflammation)

As anyone who has ever suffered with cystitis (a sore bladder) will know, it is a very unpleasant condition. Although not usually life-threatening, cystitis can be very distressing for your dog. It is important to seek veterinary advice as soon as possible since most cases can be easily treated with a short course of antibiotic tablets.

Urinary incontinence

Urinary incontinence means the loss of ability to control urination and can be caused by a variety of diseases. Incontinence is quite common in dogs but is usually more of a nuisance to the owners than a cause of distress to their pet. Urinary incontinence is more common in females than males because of the anatomical differences in the urinary tract especially the shorter urethra in the female.

Urine samples: how to collect

Tests are used by vets to help them diagnose disease in animals that are ill, which means your vet may ask you to bring in a urine sample (water sample) from your pet to help find out what's wrong with your dog. Urine samples are usually taken to check for diseases such as diabetes or cystitis. Urine samples are also often used as part of a routine health check to detect hidden disease before the development of obvious symptoms; this allows your pet to be treated earlier and more effectively.

Red blood cells carry vital oxygen around the body. A shortage of red blood cells in the circulation is called anaemia.

von Willebrand's disease (vWD)

This is the most common inherited bleeding disorder in dogs. It causes defective blood clotting due to reduced amounts of von Willebrands factor (vWF). This is a protein which helps tiny blood cells called platelets stick to each other and form an effective blood clot in the body.

Many breeds may be genetic carriers of this trait, but problems are most likely to be seen in Doberman Pinschers, German Shepherd dogs and Labrador Retrievers. Both sexes are affected equally.

Cancer in your dog - possible options

Cancer is the uncontrolled growth of abnormal cells. The speed with which a cancer spreads and the severity of the disease it causes depends on the type of tissue cell affected. As many as one in five dogs are likely to develop one of the many different forms of cancer at some stage of their lives. The risk of developing cancer increases with age. This means that, as dogs now enjoy a longer life expectancy through improved veterinary care, the number of animals with cancer has been increasing in recent years.

There are a number of reasons which may necessitate the removal of an animal's leg. The two most common of these are severe trauma, for example after a road traffic accident, or as management of a leg cancer. As a general rule, dogs cope far better with amputation than people imagine they will. Humans of course only have two legs, so losing one leg means a reduction to only one. Dogs have four legs so losing one still leaves them with three.

On a warm summer afternoon when your dog is playing in the garden they are at risk from inadvertently disturbing the local wildlife. Wasps and bees are the most common cause of insect stings in UK pets. However ants may also bite (or sting) pets. Bees and their cousins, bumblebees, wasps, hornets and ants, do not usually sting unless stepped on, touched, or molested. They are usually not active at temperatures below 13°C or on rainy days. Most stings therefore occur in midsummer around August.

Tick control

Ticks are common external parasites (ectoparasites) affecting dogs in many areas of the world. Environments suitable for tick development include forest, grass and moorland vegetation, close to wild mammals or birds on which they can feed during their immature stages. Dogs and cats most commonly become infested with ticks when they are in walking, working or hunting in these areas. Some specialised ticks can develop in kennel environments. The risk of tick bites may vary with the time of year; dogs appear to be more at risk during the Spring and Autumn periods but this varies with geographical region and tick species. Ticks may cause several problems when they bite, many of which can be difficult and expensive to treat. For these reasons, if there is any risk, it is very important to use tick control and prevention.

Vaccination protocols and safety

For a long time all new puppies and kittens were given a standard vaccination, which protected them from a number of infectious diseases. Recently a number of new vaccines have been developed and pet owners and veterinarians have begun to question the value of routine annual vaccination for adult pets.

This has led to development of the concept of tailored vaccination protocols. If your pet is not likely to be exposed to a disease there is little point in vaccinating them against it. Your vet will be able to advise you on the most appropriate choice of vaccine for your pet weighing up the benefits of protection against any risk associated with the vaccine.

Fitting in dogs - an emergency?

If you have witnessed an animal or person having a seizure (convulsion or fit), you will know how frightening it can appear. An animal suffering a generalised seizure (also known as grand mal seizure) will be unconscious. They may show violent, rhythmic movement of their legs, excessive drooling and twitching of the face and jaws. Some animals cry out and it is not uncommon for them to lose control of their bladder or bowels.

Although time seems to slow down when you are faced with a seizuring animal most seizures only last for 2 minutes or less. Seizures are not uncommon in dogs, but many dogs have only a single seizure in their lifetime therefore do not be unduly alarmed if you witness your dog having a seizure. Remember your dog does not know what it is doing during a seizure so it is important to keep you and your pet safe.

Almost all dogs will suffer from diarrhoea at some point in their lives. In most cases this lasts no more than a few days and dogs generally get better without any treatment. However, in a few cases the diarrhoea is due to a more serious underlying cause and does not resolve. EPI is one of the conditions that can result in chronic diarrhoea.

Food allergy

We probably all know people who are unable to eat strawberries or nuts due to an allergy but it isn't only people who can react to their food. Whilst food allergies are not common in dogs they can be affected too. Food allergies can produce many different symptoms, some of which can be quite distressing for your pet. No allergy is pleasant, but at least with a food allergy it is usually possible to avoid the cause of the symptoms so that your pet can lead a normal life.

Oesophageal foreign bodies in dogs

Some dogs are very greedy and any dog that thinks it is under threat of having a tasty bit of food taken away from it may swallow something without chewing properly. Dogs that scavenge are at particular risk of picking up and swallowing something they should not eat. Often scavenging merely results in an upset tummy but sometimes a piece of foreign material can become lodged in the throat. This is a potentially very serious condition and if you think your pet may have something stuck in its throat you should contact your vet immediately.

Almost all dogs will have a tummy upset at some point in their lives. In most cases this will get better over a few days without any treatment. Occasionally vomiting may be a sign of something more serious in your pet. One such disease which can cause vomiting is pancreatitis. Pancreatitis is a condition with a huge range of severity from almost no clinical signs to severe abdominal upset and even death. If you are at all worried about your pet's health please make an appointment with your vet.

Vomiting and diarrhoea

Vomiting and diarrhoea are very common in dogs. Both are symptoms of other conditions rather than diseases in their own right and there is a vast range of dog diseases in which diarrhoea and/or vomiting may occur. In many cases the problem may be successfully treated without ever pinpointing the actual cause. However, the information that you give your vet may be vital in deciding whether the case is serious enough to need further detailed investigations.

Aortic stenosis is one of the more common congenital heart defects in dogs. The condition is often discovered in apparently healthy dogs by a vet during a routine examination (such as before vaccination).

If your vet identifies a heart murmur in your puppy it is essential to have further investigation to establish the cause of the murmur so that appropriate treatment can be given early.

Canine heart testing schemes

Congenital heart diseases are not uncommon in puppies and some of these are inherited. Pedigree dogs have many inherited diseases and different breeds each have their own problems. Many dog breed societies employ testing schemes to detect individuals affected with certain conditions at any early stage of the disease at an early age. Early detection is important, not only to ensure appropriate treatment for affected dogs but also so that these animals can be excluded from breeding programmes to prevent them passing on the disease to their offspring.

Dilated cardiomyopathy (DCM)

Dilated cardiomyopathy (DCM) is a disease affecting the heart muscle. It is the second most common heart disease in dogs (after mitral valve disease). In DCM the heart is unable to contract normally and as the muscle stretches the heart gets larger. DCM affects mainly middle-aged large and giant breed dogs and some spaniels. Small breeds of dog are occasionally affected. Male dogs are more likely to be affected than females. Animals with DCM usually develop signs of heart failure and abnormal heart rhythms.

Heart disease in your dog

Heart disease is increasingly common in dogs - probably because their average life expectancy is increasing due to improved veterinary care. Some heart defects, e.g. hole in the heart, are present from birth (congenital heart defects) but only cause signs as the dog gets older. Other diseases develop later in life as a result of the effects of ageing or damage to the heart. The most common heart diseases in the dog develop as the dog ages and its heart starts to wear out.

Heart disease: drug treatment

Heart disease does not necessarily mean heart failure. Many dogs with heart disease have no outward signs of illness and are able to lead relatively normal lives without any medication. However, most heart diseases will get worse and once symptoms start, treatment will probably be required for the remainder of your dog's life.

Heart rhythm disturbance (atrial fibrillation)

There are many different heart problems that can affect dogs. Some of these affect the rhythm of the heart beat and one such condition is atrial fibrillation. This is most commonly seen in large and giant breeds of dog but can be seen in smaller dogs associated with heart disease. Atrial fibrillation does not cause any specific signs so it is unlikely that you will identify this as a cause of illness in your pet. However, any heart disease should be taken very seriously and an early visit to your vet can help to achieve a good outcome.

Investigating heart disease

It is important that your vet can recognise the early stages of heart failure (and therefore when to begin therapy, if necessary). Investigations of animals with heart disease are important to identify early signs of failure and to establish the appropriate timing and type of therapy. Heart disease and heart failure are not the same thing. In the early stages of heart disease most animals are able to cope although their heart is not working as well as normal. Animals can live with some forms of heart disease without showing any signs of illness at all. Heart failure occurs when the heart disease is more severe and signs of malfunction (usually coughing or breathlessness) develop. Investigations of animals with heart disease are important to identify early signs of failure and to establish the appropriate timing and type of therapy.

Neuro-diagnostic tests

If your pet is unwell it can be a confusing time trying to make sense of what your vet is doing and why. There are many tests commonly used in veterinary practice that help your vet to work out what is wrong with your pet. This information sheet explains what we are looking for when they perform tests to investigate an animal with a disease affecting the nervous system. Some of these tests can be done in general practice, but others are more difficult to perform or interpret and your pet may need to be referred to a specialist for these.

Neurological examination

A neurological disease is one that affects the brain or the system of nerves running throughout the body. The signs of illness can range from very mild (a weakness in one leg) to very severe (the inability to stand). In order for your vet to investigate the disease they need to know where the problem actually lies.

If your pet has difficulty walking this may be because of a problem with the nerves in its leg, pressure on the nerves in its spine (like a slipped disc) or a problem in the brain. Only by careful examination can your vet identify where the problem is likely to be in order to perform the most appropriate tests.

When a male puppy is in the womb its testicles are drawn up inside the body. After birth the testicles begin a journey from inside the tummy (abdomen) to the scrotum. Both testicles should have descended to the scrotum by six month of age and be easy to palpate. If testicles do not end up in the scrotum by this age they are said to be 'retained'. Retained testicles are a relatively common occurrence in male puppies, particularly in certain breeds. If your puppy has retained testicles we will probably recommend an operation to remove them (castration).

The life cycle of parasitic lungworms

Lungworms in dogs (Angiostrongylus)

Referring to Angiostrongylus vasorum as a lungworm is quite misleading. Although the early stages of the parasite do affect the lungs and severely infected dogs may show signs of coughing, other signs are far more common. These lungworms (Angiostrongylus vasorum) are also known as the French heartworm.

This is a parasite where the adult worm infects dogs but the young stages are carried by slugs and snails. The parasite itself may not cause the dog any problems unless present in very large numbers. However, in order to survive in the blood vessels the parasite releases substances which affect the clotting of the host's blood. Thus infected dogs are more prone to bleeding than normal dogs. This bleeding can pose a life-threatening risk to an affected pet. Thus this parasite is can be more dangerous to a dog than the more common worms that live in the intestine and it is very important to take precautions to prevent infection.

This disease used to be confined to dogs living in the South of the country (especially the South East, South West and South Wales). However, in the last ten years the disease has become much more common and has been seen in dogs as far North as Scotland. All dogs in the UK should now be considered potentially at risk.

They are caused by excessive licking at the site and are frequently caused by an underlying disease that needs to be properly diagnosed and treated. If you suspect that your dog has a lick granuloma you should seek veterinary advice as soon as possible.

Anal furunculosis (perianal fistulas)

Anal furunculosis (also called perianal fistulas) is a distressing condition commonly affecting German Shepherd dogs and occasionally other breeds. The problem is one of chronic deep infection, inflammation, discharges and ulceration around the tail base and anus. The condition may progress to involve a large area around the back end of the dog. It can be very difficult to cure or control but recent advances in treatments are proving encouraging.

Living with an itchy dog is no fun - but being an itchy dog must be worse! Atopy affects around 1 in 10 dogs to some degree. In dogs the condition can cause a variety of signs: skin disease, runny nose, itchy eyes and (very rarely) asthma. If your dog persists in licking its feet or has recurrent ear or skin infections, it may have atopy. As a general rule itchy skins do not resolve without treatment; so if your dog is scratching an early visit to your vet is advisable. Itchiness is not normal, nor is it a habit.

Hot spots (wet eczema, pyotraumatic dermatitis)

Sometimes dogs develop a sore spot on the skin which oozes and irritates. Often this develops over the space of just a few hours. The critical step in managing these spots is to stop the dog worrying them but veterinary attention should be sought to ensure there is no underlying condition that needs treatment. In most cases early treatment results in a rapid resolution of signs.

Skin fold pyoderma

Pyoderma means bacterial infection within the skin. Usually this occurs within the top layers of the skin (superficial pyoderma), and is a common medical problem in dogs. Deep pyoderma, when infection penetrates further into the skin, is much more serious and may take months of intensive treatment to cure.

'Walking dandruff' (Cheyletiellosis)

Cheyletiella infection is a form of mange that is also known as rabbit mites and walking dandruff. This is an itchy skin condition caused by small parasites living on the skin surface. The mites can be found on many animals including dogs, cats and rabbits and can be transmitted from pets to people. Early recognition is important as the condition can be simply treated.

Dogs in boarding kennels

Choosing a boarding kennel

It would probably be less traumatic for most dogs to be looked after by an experienced and reliable 'pet sitter'. Pet sitters are individuals who come to your home and stay there when you are away. They look after your dog in his or her normal environment. The majority of dog owners, however, have to rely on boarding kennels. Pet sitters are more expensive and some people may have concerns about relative strangers in their home. Taking care when choosing a boarding kennel can minimise stress for your dog, ensuring that they return home fit, healthy and happy.

Travelling with your dog

For most family dogs travelling is an exciting and often enjoyable experience. Dogs like to be included in whatever their family is doing and quickly learn that a car journey often leads to a walk. Unfortunately a few dogs find travelling very stressful because they feel frightened or travel sick. When taking any pet on longer journeys it is important that you are properly prepared.

Veterinary procedures


Endoscopy - the inside story

Sometimes it can be really helpful to look inside an animal to see what is going on. There are many ways of examining the insides of an animal: blood tests, imaging techniques (like X-ray and ultrasound) and sometimes it is necessary to operate to find out what is going on. Endoscopy is an alternative to some forms of surgery. Endoscopy is increasingly being performed in general practice and your vet may suggest it for your pet if it has a breathing problem or bowel trouble.

Samples and tests - how they help your vet

Laboratory tests are used by vets to help them diagnose disease in animals that are ill. Increasingly, they are also used as part of a routine health check to detect hidden disease before the development of obvious symptoms. This allows your dog to be treated earlier and more effectively. A very important use is to test that your dog's kidneys and liver are working properly before a surgical operation.

MR scanner

Scanning - the inside picture

The term 'scan' is often used to describe the method of obtaining an image of the inside of the body. This may be done with ultrasound (details of which can be found in a separate factsheet), which is often available in veterinary practices and may be performed at your vet's surgery. Recently, more specialised scans (MRI and CAT scans) have become widely available for pets - however it is likely that your pet would need to travel to a specialist centre for one of these scans.
