He said something about getting teeth cleaned if we need too. All he said was no training for 10 days until he's done with medicine. Try to brush his teeth and give him some dental treats and bones or chew toys. The antibiotics should get rid o any disease or infection he said. Nothing about switching dog food. BUT that is my question for you guys. This never happened until I switched to pro plan. Would that have anything to do with it? A litter after the switch is when it all started.
