Panosteitis is a painful inflammation of the outer surface or shaft of one or more long bones of the legs. It is sometimes called growing pains. Panosteitis is a condition that affects young, rapidly growing dogs. Panosteitis will be suspected if the patient shows pain when pressure is applied to the affected bone(s). The diagnosis is confirmed by X-rays, which usually show a characteristic increase in the density of the affected bones. Although this disease will spontaneously resolve, during episodes of lameness the condition is very painful. At these times, treatment is supportive, using pain medication and anti-inflammatory drugs as needed.

Parvovirus may affect dogs of all ages but is most common in unvaccinated dogs less than one year of age. Young puppies under five months of age are usually the most severely affected and difficult to treat. Clinical signs can vary but generally include severe vomiting and diarrhea; the diarrhea often has a powerful smell, may contain lots of mucus, and may or may not contain blood. Most dogs with CPV infection recover if aggressive treatment is used and if therapy is started before severe septicemia and dehydration occur.

Patent ductus arteriosus (PDA) is a heart defect that occurs when the ductus arteriosus (an opening between the aorta and the pulmonary artery) fails to close at birth. A PDA is usually diagnosed when your veterinarian hears a continuous heart murmur during a routine physical examination of your puppy. This article explains PDA and discusses signs, treatment, and prognosis for this condition.

Pemphigus is an autoimmune skin disease in which the body's immune system attacks the connections between its own skin cells. The three most common types of pemphigus are pemphigus foliaceus, pemphigus vulgaris, and pemphigus erythematosus. Treatment requires suppression of the immune system and prognosis varies depending on the type.

Perianal fistula, also known as anal furunculosis is a serious medical condition that most commonly affects German Shepherd dogs. Perianal fistulas are characterized by chronic, purulent, smelly, ulcerating, sinus tracts in the anal region and surrounding skin. More recent studies indicate that the condition is more likely caused by an autoimmune disease. Medical management with immune-modulating drugs is now the preferred therapy. In severe cases, surgery is required to debride or remove as much infected tissue as possible.

Pets may have visible or hidden disabilities that require some adjustments to their care or lifestyle to maximize their quality of life. With some support, these pets can have a fairly normal life and be just as loving as any other pet.

Pigmentary keratitis is a discoloration of the cornea due to chronic inflammation and is most common in brachycephalic breeds. In many cases, complete resolution cannot be achieved, but the condition can be stopped or slowed down if the underlying cause can be identified and treated. Surgery and medications may be used to help address the problem.

Pituitary macroadenomas are large tumors of the pituitary gland that are either functional (secrete hormones) or non-functional (do not secrete hormones). The most common functional pituitary macroadenoma in the dog secretes the hormone ACTH, causing increased cortisol levels and Cushing’s disease. Non-functional macroadenomas cause clinical signs through compression of nearby structures resulting in vision changes, diabetes insipidus, and neurologic disorders. This handout explains the effects of these tumors on dogs, how they are diagnosed, and the treatment options available.

Pleural effusion refers to the abnormal accumulation of fluid within the chest cavity. The fluid is not found within the lungs, but instead within the pleural sac, essentially meaning the lungs are floating in a chest that is full of fluid. There are several causes, including chylothorax, heart failure, and lung or chest tumors. Dogs presenting for pleural effusion are often experiencing shortness of breath and decreased oxygen intake; placing them into an oxygen cage provides some degree of immediate relief. Removing the fluid that surrounds the lungs will allow the dog to breathe more readily and this fluid can then be tested to identify the cause of the pleural effusion. The treatment and prognosis vary depending on the underlying cause.

Pneumothorax is an accumulation of air outside the lungs, but inside the chest wall. The air outside the lung prevents the lungs from inflating normally, and can lead to lung collapse. There are several variations of pneumothorax.
