Q. My dog will pant, shake, and stiffen up. This has happened 3 times. When I'm not home
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. The first thing I would recommend would be to take her to the vet for a thorough physical examination - this sounds like it could be separation anxiety, but you want to be sure there aren't any neurologic problems, or problems with pain, before pursuing behavioral issues. If everything checks out at the vet, consider using a tool such as a Thundershirt (your vet may sell them or you can check www.thundershirt.com) as a way to relieve anxiety. You didn't specify your dog's age, but if she's young crate training may also help her to feel more secure when you're not around.
