I've been taking my dogs to Country Club Kennels for years now, and I would trust them with any dog. The staff is knowledgeable and extremely conscientious, and the dogs come home happy and well-cared for. One trip I went to Japan for two weeks, and one of the dogs developed an infected paw. Country Club Kennels called their vet in to the kennel and the paw was immediately treated. I came home to find him healing, and simply paid the extra vet costs.
Plus, the dogs love it. They are treated to 8 play times out in a huge play area, and there are no extra charges for this service or for administering medicine. It's a bit of a drive from DC, but incredibly worth it.
