Giardia is a peer-shaped parasite, extremely common in retired Greyhounds. The most common symptom of giardiasis is diarrhoea, which may be chronic or intermittent. Diarrhoea tends to have an `oatmeal' appearance. Usually infected dogs do have appetite but still loose weight. Possible treatment: metrinidazole or fenbendazole. As giardia cysts can remain viable for weeks, strict hygiene is a must.
