What to Do if Dog Keeps Swallowing?
You should pay close attention if your dog keeps swallowing and licking his lips to see if there is a specific environmental trigger causing this behavior. A dog could do this if they feel threatened or cornered, such as by a small child. Sometimes your dog will do this behavior, throw up, and then be perfectly fine without other instances of excessive swallowing.
If you are unaware of any issues in the environment causing the excessive swallowing, then you should take your dog to the veterinarian as soon as you can. A complete workup will happen where the veterinarian looks at the mouth, gums, teeth, and throat to see if something is going on.
The veterinarian will want to get a lot of information from you, such as vaccine history, any possibility of toxin exposure, how long this has been going on, among many other pieces of information.
