Buster, who is soon to be 9 years old has been having some real issues with his mouth. When he was being crate trained as a pup he broke off all of his k9 teeth chewing on the bars( didn't realize it until it was too late). We went to the vet on Friday because he hasn't been eating normally, we figured out that it was because his mouth hurt and had started wetting his food. So after bloodwork and and exam they have come to the conclusion that his top k9 roots are infected and will remove them in a couple of weeks after antibiotics. I asked my vet if it would be ok to feed canned food exclusively and they said yes. Just wondering what your thoughts are on this? We are currently feed Canidae All Stages and would feed Canidae canned in place of kibble. What, if any, disadvantages would there be?
