I've never done so with my two doggy girls, but I know of 2 zoos that have tried it. One zoo guy's female dog loved it, she'd have multiple orgasms in a row. The other zoo guy's female dog absolutely hated it, it freaked her the hell out, so he didn't bother trying again. It all depends on the dog, I'd assume most wouldn't be comfortable with you holding a noisy object near their coochie, but I could be wrong.
