Why is my dog sick with bad breath, drooling, fever, acting strange?

Poor Felix! I agree, it definitely sounds like something is wrong inside his mouth. He may have a dental problem such as a broken or infected tooth, or may have a wound, a growth, or even some type of foreign body stuck there. I would strongly recommend taking him to the vet for an exam. He/she can do a thorough oral exam (with sedation, if needed) to determine what's wrong, and get him started on appropriate treatment depending on what is found.

Hello. I’m sorry for your frustration, but some further investigation by a veterinarian is needed in order to determine what is going on. A thorough oral exam to look not only at the teeth but under the tongue, and all over the inside of the mouth for evidence of any growths, foreign bodies, etc would be the first step. This often requires sedation and dental X-ray may be helpful. Leo could also have something in his sinus or nasal cavity.....something stuck in there, a growth or polyp or just a deep seated chronic infection. Sedation to examine above his soft palate and then to flush his nasal passages would be recommended. If these things are not done to try to find the underlying problem, all you can do is continue to try antibiotics. If penicillin has been tried twice, it’s time to move on to a more broad spectrum one. However, I would be concerned that there is something more going on and the additional investigation would be best.

He needs to see a vet if at all possible. His symptoms are very vague and not specific for one particular illness or disease. I cannot tell you how to treat him at home without knowing why he is sick. You really need to find a way for him to see a vet.

You should have Pete examined by your veterinarian. There may be periodontal disease, infection or foreign body causing the symptoms. Sedation may be required to examine him fully. If it is periodontal disease, a complete dental cleaning may be indicated. This will require anesthesia and Pete may need extractions.

It definitely appears that something is causing an infection in the mouth. Diseased teeth could be the cause, but could also be due to a laceration in the mouth, or a foreign object stuck in her mouth. The drooling is likely due to the mouth problem, but the shaking is a bit worrying. This could indicate pain, but in worse cases could indicate shock. Unfortunately, I would need more information and in order to determine if this is an emergency or not. For this, you would be better off having an online consult with one of our vets. This service does cost a little, but may save you in emergency fees. I hope that helps and Puppy gets better soon.

It sounds as Buddy is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti nausea injection (lip licking is a sign of nausea), antibiotics and a special food for a few days in order to get better.

Poor Rosie. This foul odor around her mouth could be due to a broken tooth or an infected tooth, and that would prevent her from eating well. It would also make her lethargic. She needs to see a vet now, please take her into one immediately.
