Why does my 6-month-old puppy have bad breath that smells like poop?

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!

It could be just normal puppy breath. Some people feel like it doesn't smell good. If she tends to eat poop, this could also be the cause. With her being so young, I would not expect her to have any dental tartar causing a smell. If it continues or it gets worse, I would have your vet take a look at the mouth to ensure there isn't an infection somewhere.

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.

Yes, this can be a sign that something is wrong with Daisy's mouth causing this smell, but it could also be due to something she is eating. Eating poop is common in puppies, and this will cause bad breath. I'd have her seen by a vet for this bad breath.

An infection or ulcers or bad kidneys can cause changes in the breathe. An infection can be under the gums line affecting the tooth root that will not be able to be seen unless there are xrays taken. I would have him seen by your vet to see if this is the case and a simple blood panel can check his kidney values for you

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.

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!
