My Pomeranian's breath smells like rotten fish. What should I do?

I would guess that this is potentially food related, and if it is transient and he is doing well on his food otherwise there may not be anything to be worried about. If it bothers you, you could try changing his diet to another flavor or another brand altogether (I recommend sticking to foods by Purina, Hill's, Royal Canin, Iams or Eukanuba). You could also consider trying a probiotic supplement. Although Guido is young he could still also have a tooth problem and if the odor seems to be around all the time you may want to have your vet examine his mouth.

It would be best to have a veterinarian do an exam on him. It’s possible he may have a wound on the roof of his mouth or back of his throat, or a piece of grass or a small twig stuck on a back tooth, etc, or a wound elsewhere in his mouth. It’s also possible that he’s having some tooth root problems with the recent eruption of adult teeth. If he is eating fine and otherwise acting normally, it’s ok to try brushing his teeth and try a rinse or water additive designed for halitosis (bad breath) in dogs. However if that doesn’t help after a few days, I would strongly recommend that you take him in. Thanks for asking Petco Pet Education Center, formerly Petcoach!

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!

Thanks for using Petco Pet Education Center, formerly Petcoach! Bad breath could be a sign of a bad tooth. Smelling like fish could be Iayl licking his anal glands (sacs inside the rectum). If these glands get full or infected, cats will lick the area. I recommend taking Iayl to the vet for an exam of his mouth and anal glands. He may need to have a dental cleaning or have the glands expressed. Good luck!

At his age, the bad breath could be an abscess or the normal shedding of his puppy teeth. Take a good look inside his mouth to check for any abnormalities. You may also consider having him examined by the veterinarian if you are not sure what you are seeing. Otherwise, I recommend to brush his teeth. This is one of the best ways to maintain dental health: https://www.petcoach.co/article/brushing-teeth-home-dental-care/ I hope this helps and please feel free to post any additional questions.

It's odd that it improved when the [Giardia](https://www.petcoach.co/dog/condition/giardia/) was treated. My first suspicion for the ongoing odor is that she may be licking at her anal glands or eating her own (or someone else's) poop. Ideally, have her examined by a veterinarian just to make sure there are no wounds, irritation, etc in her mouth or throat that maybe contributing. You r vet can also check her anal glands to see if they seem full or irritated which could lead t her having a tendency to lick at them a lot. If her anal glands are fine, and her mouth is fine, use a daily product for dental health. [CET products](https://us.virbac.com/cet-veggiedent-fr3sh-dental-chew-for-dogs) contain chlorhexadine which kills bad breath causing bacteria. [Water additives](https://www.petco.com/shop/en/petcostore/product/zymox-oratene-water-additive) are great too. I hope thats helpful for you. Thanks for asking PetCoach! Good luck!

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Fishy smelling breath can be from either dental disease or from GI disease. If she is having a hard time breathing, it could be either heart disease, primary lung disease (airway disoders, asthma, infection/pneumonia, etc.). She could also be breathing up from pain, especially if she has GI disease, this can make them have abnormal breathing as well. I would be fairly worried and would recommend bringing her to a vet right away. I would bring her to an emergency clinic if your vet isn't open. Best of luck with Luna, I hope she feels better soon!
