hm my puppy got a bit of a smelly breath lately. shes on a very good diet, fruits vegetables as well as kibble and soft food since the day we got her.and that was never a problem. she is 5.5months now l wonder if that is because she is teething now? found some teeth recently and saw a bit of blood on her gums. not sure how to help her through that stage and also how to fight the doggy breath smell?
