Mr. Mcgoofy cAme from a shelter. he is the love of my life. But ever since we got him front leg will twitch. kind of jerk every so often. When when he is lifting it to groom. I asked the vet about it when we first got him he said it was a nervous jerk. he has been with us two and a half years now and he still does it.he is in a very stress free environment, and is spoiled to the hilt. he does it when he's just laying on me or on the ground it doesn't matter. Should I be worried.
