Thanks everyone

Deb-Yeah I have heard of alot of rotties with knee problems, Im sorry yours is going through it

I think Boxers are prone to hip dysplasia(along with MANY other things ), but I have never heard about them being more likely to develope knee problems, be it could be something like that.

I called the vet today and she told me that his pills wouldn't have anything to do with it and that if it keeps happening to bring him in.

It hasn't happened all day today though

Thanks again everyone
