Why does my dog's tongue stick out one side, making drinking hard?

Poor pup! It sounds like she may have a neurologic issue of some kind that is causing her to have trouble getting water into her mouth and swallowing. She could also have severe dental disease, or a wound or tumor inside her mouth causing the problem. I would recommend having her examined by a vet right away - he/she can do a thorough oral exam to check for any problems in her mouth, and also check her reflexes and neurologic function for any abnormalities.

He has a very short snout, so this may be because his tongue is too long and there is not enough space for his tongue inside the mouth. This is very likely, especially if he can freely move his tongue. If his tongue appears paralysed you need to take him to your veterinarian for an exam to find out why. There could be various reasons for this.

Poor Thor! I am concerned that he could have a problem with the nerve that innervates his tongue or he could have something like masticatory myositis which affects the muscles of the jaw. Usually with masticatory myositis, the dog will be painful when the mouth is fully opened. If the antibiotics and steroids do not help than consider taking him to a veterinary neurologist or internal medicine specialists for a work up and treatment. If he is not able to drink than your vet can give him subcutaneous fluids to help keep him hydrated.Hope he feels better soon!

Depending on which teeth and how many are removed it is not uncommon for some dogs to not be able to keep their tongue in after extractions. This can also be a nervous behavior or a sign of nausea. It is unlikely neurological if there are no other signs such as difficulty swallowing or blinking or any changes in facial symmetry

Unfortunately this is just how she was made and nothing can really be done to prevent this. This is a common problem in short nosed breeds like pugs. They usually have the same tongue length as normal dogs but not enough space to store it. I think she is quite a cutie pie!

Dogs (and humans) can't swallow their tongues. It is firmly attached to the mouth. They can curl it up quite a bit, but it isn't causing any issues. If you are concerned about Rosie, I would have her examined by a vet.

Nancy may have an infected tooth in her mouth that is causing the discomfort and fever. I would recommend taking her to the vet to have an oral exam performed to look for a problem. You may also want to feed her soft or canned food until you determine the problem because thenkibble could further irritate the problem.
