My dog is drooling, has bad breath, and cries when I touch his jaw.

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.

These are very serious signs and indicate dehydration and also possibly an injury or fracture to the jaw. He should receive urgent veterinary assessment in order to assess the jaw and start appropriate treatment in order to maximise the chance of a full recovery

Poor Rufus! Unfortunately there are no OTC pain medications you can give him, as many are toxic to dogs and can be fatal if given. I'd take him into a vet as soon as possible to be checked out and get pain medication. If he's extremely painful, I'd rush him into an ER vet. Until he sees the vet, rest him as much as possible. Take him out to potty on a leash, and bring him right back in when he's done. Best of luck, I hope this helps!

It sounds like this tooth is really hurting Meatball! The only way to get him to calm down is to have this tooth treated, and to administer pain medications. Unfortunately there are no OTC pain medications you can give, many human ones are toxic to dogs and can be fatal if given. I would take him into a vet today for this problem, from your description of his behavior, he is showing you he is in a lot of pain and is very uncomfortable. This is not something that should wait to be treated. Please take him into a vet now, best of luck!

Poor Baby! It sounds like he may be suffering from some neck pain. This could progress causing neurological problems if left untreated. I would have your vet take a look at him to localize the pain and to ensure nothing else is going on. Your vet will be able to do x-rays if needed. In the meantime, I would keep him confined and do not let him jump, run or play until you can get in to see your vet. I would not give him any human pain meds as most are toxic to dogs. I hope this helps.

Oh no poor Cody! It does sound like he is in pain at the moment, and he could have injured himself somehow. I would leave him be for tonight and rest him, don't try to look in his mouth because you don't want to get bit, and monitor him. Should he still be acting like this in the morning, I would take him into a vet right away. The vet can do a physical exam, lameness exam, blood tests, urinalysis, and x-rays to diagnose what is causing his pain. Once the cause is found, the vet can discuss treatment options. He would likely benefit from pain medications, which the vet can prescribe, but please do not give him any human ones. They are toxic to dogs and can be fatal if given.

Sounds like Apollo is in pain. Rest him tonight. No running, jumping, or playing. Take him out to toilet on a leash, and bring him right back in when he's done. If he still appears painful in the morning, then I would take him into the vet for an exam. The vet can diagnose where the pain is coming from, and can dictate a treatment plan for it. He may also benefit from some pain medications, which the vet can prescribe. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given.
