What to do if my dog won't eat and has a possible toothache?

Your dog needs to be seen by a veterinarian right away. He could have an infected tooth/teeth and need extractions and a dental cleaning as soon as possible. Infected gums and teeth can introduce bacteria into the bloodstream that can adversely affect your dog's heart. This problem needs to be addressed now.

Rex urgently needs to be seen by your veterinarian for an exam. You likely will need to schedule a dental cleaning under anesthesia. He likely has a very painful tooth root abscess. The vet will remove all tartar, and also clean under the gingiva wich will also remove bacteria which are causing infection and bad breath. He will also remove all rotten and infected teeth. This should greatly increase your dog's quality of life and will help prevent heart and kidney disease. He will also be able to eat properly without a toothache! Please make an appointment on Monday!

It's highly likely to be a teeth problem, either something stuck in his gums causing an inflammation or a bad tooth that needs to be removed, you will need to take him to the vet ASAP (it can wait for tomorrow) in order to get it checked and treated, bring him to the vet fasting (8 hours) in case they need to sedate him to the check the oral cavity or do a dental procedure.

Yes, this will be causing Squeakers pain and discomfort, and it's not normal. It suggests severe dental disease. This can be treated by a vet by having the teeth removed, and the vet can do a dental cleaning, scaling, and polishing. I'd take him into a vet in the morning. I hope this helps!

If you are sure it is her teeth, have her examined by your veterinarian. Periodontal disease can lead to systemic disease, bad breath or tooth loss if left untreated. If she has any degree of periodontal disease, she will require anesthesia for a dental cleaning and any periodontal treatment. Your vet should perform a complete exam and blood work to confirm your dog is a good anesthetic candidate. Periodontal disease typically does not present as you describe so a visit to your vet is highly recommended. The GI upset can be managed by withholding food for 12-24 hours. Allow small amounts of water or PediaLyte. Resume feeding a bland diet (1:1 ratio of plain boiled boneless chicken and plain white rice). Feed in small, frequent amounts waiting at least one hour between feedings. If the vomiting stops, transition slowly to the regular diet. If not, see your veterinarian.

There are a number of things that could be wrong with those symptoms. A broken tooth can be very painful and lead to infection, while a heavy flea infestation could cause anemia or other underlying illness.
