Breath: Oh Yuck! Dog Breath.

• Most often, bad breath is caused by dental or periodontal disease. Some dogs do not adequately chew their food; thus they don't clean their teeth naturally by the chewing process. Also, some dogs are just prone to dental plaque, tartar and disease.
• Internal diseases such as kidney disease can also cause bad breath (of course there will be other symptoms besides just bad breath.) Check with your veterinarian.
• Also, we do not recommend only a wet or can food diet.
