Like all living things, your Bedlington puppy has a heart, and, as with all other living things, your Bedlington puppy may either have or may develop problems with their heart. 

Heart conditions, particularly heart murmurs, are not common in this breed but you should be aware of the possibility and have your Vet check heart function at the first opportunity. A Wurroit puppy comes with a full health check including information about heart and lung function. This information (along with more general health information), is provided to you as a checklist on a form completed and signed by our local vet.

Some heart problems are congenital, ie, developed while in the uterus while others develop after birth and may be the result of diseases, infestations such as heart worm, or the more usual processes associated with aging. In most cases, heart conditions will be detected by your veterinarian during your usual Vet visits. Most Vets will automatically assess heart function during routine visits and prior to vaccinations.

Things to be aware of which may indicate the onset of heart problems include;

Elevated respiratory rate,

Cough,

Rapid tiring,

The development of a Pot Belly, and

Fainting.

Please note that some of the above conditions may also be associated with other diseases and conditions such as Cushings Disease. Where you have some concern regarding your pup we strongly advise a Vet assessment as the primary means of diagnosis.

Prevention

As always, the best form of "treatment" is prevention. Preventive actions include;

Ensuring your dog gets plenty of regular exercise, where possible, include some running activities so that the heart has to work to capacity,

Ensure your dog has a healthy and appropriate diet, this will ensure your dog has the energy needed for an active life which will assist in the maintenance of heart health,

Look after your dogs dental health, some studies have shown that Periodontitis has been linked to the development of Congestive Heart Failure and Endocarditis while other studies identify very little evidence of association between Infective Endocarditis and Periodontitis.

These actions either singly, but especially in combination, will assist in maintaining heart health. 

Most Common Heart Problems

The most common Heart Conditions in dogs are Mitral Valve Insufficiency and Infective Endocarditis. It is estimated that as many as 1 in 10 dogs will suffer from some form of heart condition throughout their lives, in some cases this will have no or minimal impact on the dog. In other situations the progress of the "condition" will be quite rapid resulting in congestive heart failure.

As with the human heart, a canine heart is divided into the left and right sides with each side having two chambers, the atria and the ventricles. The heart also has four one way valves to ensure that blood flow follows a "prescribed" direction. Where these valves fail to completely "seal" blood will "regurgitate" into the chamber resulting in abnormal heart sounds producing a distinctive "mumur".

Blood returning to the heart from the body flows into the Right Atria, then into the Right Ventricle and is then pumped to the Lungs for exchange of CO2/O2, the tri-cuspid valve prevents blood from flowing from the ventricle back into the atrium. Re-oxygenated blood returns to the Left Atrium, then into the Left Ventricle and is then pumped out to the body. The Mitral Valve, situated between the Atrium and the Ventricle prevents blood flowing back into the Left Atrium from the Left Ventricle.

From the preceding link:

There is actually little evidence that periodontal disease is a frequent source of infective endocarditis in dogs, in apparent contrast to humans. Other predisposing facotrs for endocardidtis in dogs include other chronic sources of bacteremia (e.g., urinary tract infection, diskosponsylitis) or systemic illness that facilitates bacterial infection (e.g., diabetes mellitus, Cushing's disease)
