Hi, my guineapig (nearly 7 yrs old) has a runny nose in one nostril and has done for well over a month. He has overgrown back teeth, as you can read in my previous post. I took him to the vet 3 weeks ago who basically said he hasn't got long to live (2 months would be lucky) and just to nurse him until he did. However I don't want to do that, when his teeth get really bad I'm going to risk the GA to give him a chance. Since then he's put on 225g and is, touch wood, quite bright, apart from having a runny nose in one nostril and of course still overgrown back teeth but is eating ok. I did point this out to the vet 3 weeks ago but she pretty much dismissed it. I have already given him a full course of baytil for it and this hasn't cleared it up (my other guineapig died about 2 months ago of pneumonia so had it left over). My question is what do they usually give guineapigs to clear it up? As baytril didn't seem to work. Also it's only in one nostril and his eyes are ok, surely if it was an upper respiratory infection it would be in both nostrils?
