Common conditions of pet rabbits include upper respiratory tract infections, internal and external parasites, dental disease, E. cuniculi infection, gastrointestinal stasis, uterine problems, and pododermatitis (sore hocks). This article discusses causes, signs, and treatments for these conditions. Regular yearly check-ups enable an early diagnosis and treatment of some rabbit diseases. Whenever a rabbit stops eating, for whatever reason, it is important to take them to see your veterinarian immediately for an evaluation.

The ear mite is a surface mite that lives on cats, dogs, rabbits, and ferrets. It is usually found in the ear canal but it can also live on the skin surface. Mites are barely visible to the naked eye. Clinical signs of infestation vary in severity and may include ear irritation, leading to scratching at the ears or head shaking, dark waxy or crusty discharge from the ear, areas of hair loss resulting from self-trauma, a crusted rash around or in the ear, and an aural hematoma. Your veterinarian will advise you about which insecticidal products are suitable. Your veterinarian may want to re-examine your pet to ensure that the mites have been eliminated after the initial treatment has been performed.

Echinococcosis refers to being infected with a tapeworm of the genus Echinococcus and is primarily a parasite of coyotes and foxes. Infected dogs are usually asymptomatic, but in both dogs and humans the parasite can cause large cysts to form within the lungs and liver. E.multilocularis is treated with praziquantel and in most cases the prognosis is good.

Encephalitozoonsis is a parasitic infection that can affect the kidneys, eyes, and nervous systems of rabbits. Many infected rabbits do not develop clinical signs until they are older or if they become stressed or immunocompromised. Common signs that may develop include heavy white plaques/growths inside one or both eyes, head tilt, eye twitching, and tremors or seizures. Treatments are available, though not all rabbits respond.

Esafoxolaner + eprinomectin + praziquantel is given topically on the skin to treat and protect against various internal and external parasites and prevent heartworm in cats. Side effects are rare but may include hair loss at the application site, gastrointestinal upset, skin reactions, or neurologic signs. Use caution in sick or underweight cats. If a negative reaction occurs, please call your veterinary office.

Demodicosis is a parasitic skin condition caused by Demodex mites. These microscopic mites can be found on the skin of all animals but, in some cases, they multiply to excessive levels and cause clinical signs. Signs vary depending on the species of mite involved, though generally involve hair loss, skin inflammation, and crusting. Demodex mites found on cats and dogs do not spread to humans.

Ferrets are commonly affected by ear mite infestations. Many ferrets show no symptoms of infestation but you may notice your ferret shaking her head or scratching herself. Treatment for ear mites must be done under the guidance of a veterinarian familiar with ferrets.

Despite common belief, an average cat experiences only minor skin irritation in response to flea bites. Even in the presence of dozens of fleas, there will typically be minimal itching. On the other hand, a cat with flea allergies will have a severe reaction to even a single flea bite. Affected cats experience intense itching and will chew, lick, or scratch the affected site(s) nonstop, causing hair loss and possibly open sores or scabs on the skin, allowing a secondary bacterial infection to develop. Strict flea control is the foundation of successful treatment. There are many highly effective flea control products for treating the cat and controlling fleas in the environment.

Flea allergy dermatitis is a common cause of allergic reactions in dogs. The antigens in flea saliva cause an intensely itchy response in sensitive dogs. Itching and hair loss in the region from the middle of the back to the tail base and down the rear legs (the flea triangle) is often associated with this allergy. Strict flea control is essential for treatment and prevention.
