If my vacation is in the state where I reside, then he almost always comes with us. This would consist of camping up north, or at a house on Lake Michigan.
We're fortunate enough that our dog trainer will board him (she's 20 minutes from us), and if she's not available then we have our breeder who is an hour away. My dog loves going to both places, as he runs around and interacts with other dogs the whole time we're gone. He's always exhausted sleeping in the car on the ride home.
