My 4-month-old puppy has fishy breath. Should I be concerned?

Question

Hello, I have a 4 month old terrier mix puppy who is teething. The last two days he has developed very fish smelling breath. Is this normal or is it something I should be concerned about? Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 25 lbs

AS long as he is eating normally, I don't think you need to be too concerned. Has he been licking at his back end? Anal glands can smell "fishy," so that may be the issue. Yuck! :/ Its not urgent if he is otherwise normal, but get him in to your vet when you can so they can do an exam and make sure nothing is wrong. They can also check and express his anal glands if needed. Thanks for asking Petco Pet Education Center, formerly Petcoach!
