am upset & desperate for an answer? My dog is a 2yr old Golden Doodle, and perfectly healthy. Up until 5 days ago we noticed that he is having little spasms that occur in his upper lip/ or also known as his upper muzzle. Its only occring when he is chewing on his bone, milk bone treat, or yawning. If it occurs when he's yawning it will usually interrupt his yawn and his upper mouth/ upper lip with twitch for 2 to 3 seconds. Other than that we've been noticing that he is drinking quite alot of water. My vet didnt run an tests and did NOT even do an oral exam and he just told us its a chewin gum seizure. I'm thinking it could be more of a tooth that is hurting, chipped, or injured or even his jaw. I need help or answers please!
