What is Keeping His Mouth Open?
A dog can have many different expressions throughout the day and night. He may also do some odd behaviors and have different, atypical expressions. A dog may keep his mouth open for a variety of reasons. If he is keeping his mouth open and he doesn’t normally do that particular behavior or expression, then you may notice it immediately.
You may also notice if he is panting when his mouth is open, or looks as if he is having trouble breathing or is congested. If your dog is keeping his mouth open, and is not willing to close it, then you should contact your veterinarian. Causes can include:
Your Dog Could have a Neurological Problem
If your dog suddenly starts opening and closing their mouth, it could be a sign of a neurological problem. This repetitive behavior is often seen in dogs that are having a seizure, and it can be quite distressing for both the dog and their owner.
In some cases, the dog may also appear to be “fly biting” – snapping at invisible insects. If your dog is showing any other signs of a seizure, such as loss of consciousness or muscle tremors, then you should seek veterinary advice as soon as possible.
However, if they are only displaying repetitive jaw movement, it is still worth getting them checked out by a professional to rule out any underlying health issues.
Why is my dog behaving badly all of a sudden?
If your dog is showing increased aggression “all of a sudden” or just seems “off,” it’s always a good idea to talk with your vet. Your dog might be in pain or acting out because of an ear infection or arthritis or something more serious.
