Respiratory disease is common in birds and can be caused by infection with bacteria, fungus, or parasites; by exposure to aerosolized toxins or environmental irritants; or by pressure on the respiratory tract from enlarged organs or tumors. Birds can have varying signs, such as coughing, sneezing, ocular or nasal discharge, or difficulty breathing. Any bird showing respiratory tract signs should be examined and tested by a veterinarian as soon as possible. Over-the-counter medications from pet stores are not recommended for treating sick birds.

Cryptorchidism is the failure of one or both testicles to descend into the scrotum. Some purebred cats are more at risk, but it can affect any cat and is believed to be an inherited trait. Diagnosis can usually be made by palpation but sometimes requires blood testing or abdominal ultrasound if the cat’s history is unknown. Risks of retained testicles include testicular cancer, spermatic cord torsion, and the development of undesirable male characteristics, so neutering is strongly recommended. Surgery is generally routine, and recovery is similar to any abdominal surgery.

Cryptorchidism is the failure of one or both testicles to descend into the scrotum. Toy breeds may be more at risk, but it can affect any breed of dog and is believed to be an inherited trait. Diagnosis can usually be made by palpation but sometimes requires blood testing or an abdominal ultrasound if the dog’s history is unknown. Risks of retained testicles include testicular cancer, spermatic cord torsion, and the development of undesirable male characteristics, so neutering is strongly recommended.

Retinal detachment can cause sudden blindness or vision changes. It is generally secondary to an underlying condition like high blood pressure. Diagnostics and treatment are discussed. Prognosis is guarded to good depending on the underlying cause.

Some dogs have a condition known as paroxysmal respiration, more commonly called reverse sneezing. With this condition, the dog rapidly pulls air into the nose, whereas in a regular sneeze, the air is rapidly pushed out through the nose. The dog makes a snorting sound and seems to be trying to inhale while sneezing.

Ringworm infections in cats are caused by a fungus, not a worm. They can be easily recognized, though definitive testing by fungal culture is recommended. Ringworm is highly contagious and can be spread between animals and from animals to people. The clinical signs, diagnosis, treatment, and risks are explained in this handout.

Round cell tumors are among the most common skin tumors in dogs, and they typically form just under the skin, although they may change the surface of the skin above them. It is impossible to diagnose any of them without a veterinary pathologist analyzing a tissue sample of the tumor under a microscope. If detected early, most round cell tumors can be easily removed.

A salivary mucocele is an accumulation of saliva that has leaked from an injured salivary gland or duct. Some mucoceles cause swelling of the face and neck, while others interfere with a dog’s ability to swallow or breathe normally. Treatment typically requires surgical removal of the affected salivary gland(s).

Sarcoptic mange, also known as scabies, is caused by a parasitic mite that burrows just beneath the surface of the skin. The presence of the sarcoptic mite causes intense itching; an affected dog will constantly chew and scratch his skin. Sarcoptic mange is highly contagious to other dogs and humans.
