  • 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.

  • Chronic upper respiratory tract disease in cats results from long-term inflammation of any part of the upper respiratory tract. It can occur for a variety of reasons. Common signs include sneezing, nasal or eye discharge, and noisy breathing. It is often associated with chronic viral infections and secondary bacterial infections.

  • Chylothorax is a relatively rare condition in cats in which lymphatic fluid (called chyle) leaks into the pleural cavity (an area between the lungs and the inner lining of the chest wall), causing lung compression and the inability of the lungs to fill with air. This occurs more commonly in purebred cats. The causes, diagnostics, treatments, and prognosis are explained in this handout.

If a negative reaction occurs, please call your veterinary office.

  • Ciprofloxacin is a systemic fluoroquinolone antibiotic used to treat bacterial infections. It is often given by mouth, but an injectable form is also available. The most common side effect is gastrointestinal distress, but other side effects are possible. It is contraindicated in young or dehydrated pets, or in pets with liver or kidney disease. It should not be the first-choice fluoroquinolone for veterinary patients.
