We always send Monty dog to a kennel. He seems to like it there. When we drop him off, the girls who work there come running up to him and he runs right to them wagging his tail , and excited to go into the "kennel area". He gets several playtimes a day in a large room with a lot of toys. He also seems to enjoy being so close to other dogs.
Its funny, I see a lot of older dogs getting dropped off who look horrified, and then this 12 lb little Jack Russell runs in and charges past them to kiss the caretakers.
At the end of his stay , he gets a report card that tells us how he did and how well he ate, played, went to the bathroom etc.
He's only gotten bad marks in anything twice!

One time he nipped the groomer and one time he did not eat his food (nothing odd though, he isn't a big eater).
It is expensive. Costs us about $40 a day for all things included.
But we do not know anyone who could dog sit, and I'm not comfortable inviting a stranger into the house. Also, Monty is still only a little more than a year and he needs constant supervision.
