Health is in general an insecure issue in Internet discussion. Usually some measures are taken to prevent people from treating themselves (in this case their pets) using the Internet instead of seeing the doctor (veterinarian). Should questions like "My pet has such symptoms, what can it be? How it is treated?" be asked here?
On the other side, I know some cases when such Internet advices helped a lot. There are some veterinarians who don't really know what they are doing and won't admit it. The advice to take other opinion might spare a pets life. Other veterinarians might be open to some ideas brought by the owner of the pet who read them on the Internet, for example additional laboratory test.
There also is a risk that behavioral questions will turn into health questions, like some strange behaviour (e.g. eating soil) being a symptom of disease.
I have no strong opinion on this issue, but I think it should be discussed separately for the pets site. Similar problem was discussed for other site here: https://area51.meta.stackexchange.com/questions/6037/legal-medical-questions-disclaimer
