Giardia

Giardia is not a worm. It is a tiny single-celled parasite that can live in the intestines of dogs, cats, and humans. It is seen most commonly in dogs coming out of kennel-type situations (pet stores, shelters, dog pounds, etc.). Symptoms include intermittent diarrhea, weight loss, depression, and loss of appetite. Diagnosis is made from a very fresh fecal specimen that must be collected at the veterinary clinic. Treatment is an oral medication administered at home. Prevention involves careful disposal of all fecal material and cleaning contaminated areas- This prevents re-infection. Humans can become infected with Giardia so special care must be taken to wash hands and utensils.
