Medical Conditions

  • Chronic egg-laying occurs when a female bird lays one egg after another or lays repeated clutches of eggs. Chronic egg-laying may lead to malnutrition and egg binding. There are both behavioral and medical interventions to stop chronic egg-laying.

  • Chronic lymphocytic leukemia is a slowly progressing cancer of a type of white blood cell called a lymphocyte. It can develop at any age but is more typically detected in middle-aged to senior dogs. It also seems to be more prevalent in German Shepherds and Golden Retrievers. This disease is often asymptomatic and detected on routine lab screening. Further diagnostic procedures, as well as treatments and prognoses, are described in this handout.

  • Clostridial enterotoxicosis is a complex and poorly understood syndrome characterized by diarrhea that is associated with the bacteria Clostridium perfringens (CP). It is associated with either acute or chronic diarrhea. Clostridial enterotoxicosis is not caused by the bacteria directly, but rather by a toxin produced by the bacteria. Most cases of intestinal bacterial overgrowth are treated on an outpatient basis using antibiotics, nutrition, and probiotics.

  • Coccidioidomycosis is a fungal disease caused by the soil fungus Coccidioides immitis or Coccidioides posadii. The early signs of coccidioidomycosis include fever, lethargy, poor appetite, coughing, and joint pain. Diagnosis is by biopsy of lesions or blood testing for antibodies to the Coccidioides organism. The prognosis for recovery is dependent of the extent of lesions in the cat’s body.

  • Collie Eye Anomaly (CEA) is a genetic mutation affecting many breeds that causes developmental defects in the eye that can lead to vision deficits or blindness. This defect can be diagnosed by a veterinary ophthalmologist between 6 and 8 weeks of age by visualizing spots of choroidal hypoplasia or a colobomas . It can be associated with microphthalmia or enophthalmia. It can lead to retinal detachment and blindness. Although laser repair of partial retinal detachments can be attempted if detected in early stages, there is generally no treatment for CEA. Vision varies depending on the extent of the lesions and some dogs will become blind. Prevention requires not breeding animals that carry the mutation and this can be achieved through genetic testing of breeding dogs.

  • Color dilution alopecia is an autosomal recessive genetic disorder that affects dogs with dilute-colored coats causing hair loss. Some dogs will also be affected by secondary bacterial infections so topical management and pruritus treatments may be needed to improve the dog's comfort. Affected dogs and their relatives should not be bred.

  • Pet birds often become ill when they are not cared for or fed appropriately. Birds can develop infections with bacteria (e.g., Chlamydia psittaci) and parasites (e.g., Giardia). They also commonly suffer from reproductive problems (e.g., egg binding and tumors) and feather-picking. Birds on all-seed, high-fat diets may become obese and develop fatty liver syndrome. Older birds may develop cloacal papillomas or cancer. Your veterinarian familiar with birds will formulate an appropriate diagnostic and treatment plan if your pet bird becomes ill.

  • Turtles may be affected by one of the following diseases: metabolic bone disease (MBD), vitamin A deficiency, respiratory diseases, abscesses, shell infections, shell fractures, and parasites. Improper diet, poor water filtration, and lack of UV light are contributing factors for many aquatic turtle diseases. Seek immediate veterinary care if your aquatic turtle shows any deviation from normal.

  • Turtles may be affected by any of the following conditions: metabolic bone disease (MBD), vitamin A deficiency, respiratory infections, abscesses, shell infections and fractures, and parasites. This article outlines typical signs and treatment for these common conditions. Seek immediate veterinary care if there is any deviation from normal in your pet turtle.
