Your dog’s behavior when it is yawning may be telling you something about its health. When dogs Yawn, their paws hit the floor, and they are ready to do some exercise. They may also sniff the floor for anything that might be hidden there, like food or a ball of hair. If it starts sniping at you while it Yawns, it probably wants to tell you something, and it may be a symptom of an underlying health problem. Or maybe it’s just hungry, and you shouldn’t worry about it. If your dog has no other symptoms and its eyes are blue, then it could mean that it needs to go to the vet.
