Bad breath can develop from infected teeth, dental disease, underlying systemic disease, or genetic predisposition. Puppies have distinct, sweet smelling "puppy breath" that is completely healthy and normal. In some dogs, foul smells can indicate an infection in the lower lip fold. Unfortunately, this hard-to-find infection can be mistaken for bad breath.
If your pet's breath has a distinct fishy or ammonia-like smell, see your vet immediately. This "uremic breath" occurs in very sick pets with chronic kidney failure.
- If your pet has otherwise healthy teeth, you may try a water additive, tooth brushing or dental chews, available at pet stores.
- If bad breath is a reoccurring problem, consult with your vet.
