Brandy played too hard this weekend and was really limping on that back leg again, so that always makes me worry. I was telling a co-worker about it and he said that he had a dog with similar problems. He started feeding the dog a can of tuna every other day and they never really had a problem after. I know the Omega 3's are good, but I just can't imagine tuna being all that great for a dog. Has anyone had any experience with this? I'm thinking it would be better just to do fish oil if that were the case.
