This pad does a good job of warming my old dog's bed up for her. It's nothing fancy, but it does what it's supposed to do. The circuit breaker on the power cord is a good saftey feature. The cord has a "chew resistant" covering, but I imagine a good sized pooch could gnaw right through it,so it would be wise to tuck the cord out of the way if you have a dog that's prone to chewing.
