Why does my dog's bad breath and mouth problem keep returning?

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!

These are all signs of a pretty severe dental disease and infection. Pus in the mouth and foul odor are usually the tell-tale signs. I would suggest getting financial assistance b/c this can be a huge undertaking to get a pets teeth cleaned and diseased teeth extracted, but this is the only way to correct it once the teeth are this far gone. Here are some financial resources I am hopeful can help here--> i would first start with carecredit listed at the very bottom. Red Rover: https://redrover.org/find-financial-assistance-veterinary-care Best friends: http://bestfriends.org/resources/financial-aid-pets AVMA: https://www.avma.org/public/YourVet/Pages/Financial-assistance-for-veterinary-care-costs.aspx HSUS: http://www.humanesociety.org/animals/resources/tips/trouble_affording_veterinary_care.html PAWS: https://www.paws.org/cats-and-dogs/other-services/help-with-veterinary-bills/ Your dogs friend: http://yourdogsfriend.org/we-recommend/need-help-paying-vet-bills/ AFRP: https://www.animalfriendsrescue.org/financialassistance.html Speaking for Spot: http://speakingforspot.com/?p=Financial%20Assistance%20for%20Veterinary%20Care 3 options for financing include www.carecredit.com, www.scratchpay.com and www.vetbilling.com. The first two companies have low interest APR rates (starting at 5%) and allow you to pay for a vet bill over 6-24 months. The last company offer a billing option for veterinary clients through automatic bank account drafting on a predetermined date at the time of service. Care Credit checks your credit but Scratch Pay does not, making it a good choice for owners who may have been declined for Care Credit in the past. I wish you the very best in getting Dixie's dental disease resolved through a proper dental prophylaxis and removal of all diseased teeth. She will feel so much better after her procedure and also she will be healthier for it. Best wishes moving forward. Take care. : )

Halitosis is the word we use for bad breath. It is most commonly caused by dental disease. I am attaching a handout below with more information on halitosis. http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=129 Since Luckyboy appears to have some pain in his mouth, I would definitely recommend having him evaluated by your veterinarian. In order to determine the severity of his dental disease, they will need to perform a dental under anesthesia so they can fully evaluate each tooth under the gumline. If they find a broken, painful or infected tooth, they will be able to remove that tooth and resolve Luckyboy's pain. I am attaching a handout below that discusses periodontal disease. http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=222 Good luck! I hope that was helpful and that Luckyboy will feel better soon. Thanks for using PetCoach.

This sounds like severe dental disease with gum loss and loose teeth. The chattering of the jaw is a sign of pain and you should have him assessed by your vet as soon as possible to remove any further damaged teeth and clean the rest of them

I recommend getting her seen by your vet for an oral exam. There may be some hidden oral disease you cannot see, she may have a tumor or polyp somewhere in her mouth or nasal passages, kidney disease can cause bad breath, there are a number of possibilities. You vet will do a thorough exam, possibly bloodwork and based on these results, be better able to tell you what is going on with your dog and how best to treat it.

If the antibiotics have not made a difference, recheck with your veterinarian. Rex may have significant periodontal disease. A complete dental cleaning may be necessary. This will require anesthesia, so pre anesthetic blood work should be done to assess major organ function. This blood work can assess kidney function which can also be the cause of his condition.

If Tehya's teeth are fine, I would recommend getting blood work on her to make sure her kidneys are ok. Sometimes with kidney disease they can have a bad smell from their mouth. I would also discuss with your vet about potentially performing a dental procedure with x-rays to confirm there is no abscess we can see.
