Oh sweetie, I think your dog had a seizure. You need to take him to the vet and let the vet know this, they can give your dog medication for this. Good luck.
My dog fell on the ground and was thrashing from pain, rolled around and hit things, breathing rapidly with his tongue sticking out. It lasted fifteen minutes. We petted him till he calmed down. Help?
Hey that is normal for a lot of animals so they probably have health problems.
