I am posting on here for one of our agistees about their pony. He has had a cough for about two weeks now, he gets a bit of a runny/pus nose also. But he is not showing signs of anyhting, he is happy as larry, eating normal, everthing normal except he coughs and has runny nose. The vet came out on Tuesday and so far she thinks it is an allergy to something, so he is getting his hay watered down before eating and a very wet hard feed. So far nothig has changed apart from the fact that it seems he is actually getting worse';' I think the vet is coming again tomorrow to see him. Would you know what this is? from any experience you may have had with something similar.
