We went on vacation and the only option we had was to put Jake in cold storage, i.e. kennel. We found one close to us and they had a very nice offer to kennel Jake for a day for free. We tried, and Jake did not seem to object. He was happy and perky when we picked him up. No negative reactions we visible. The place look clean and did not smell. Well, if there are dogs, there is smell but it was not objectionable.
So, we provided the kennel with his food, crate liner, toys, and chewables, and left the dog there. He went in with tail wagging.
When we came back, he greeted us like a dog should. He was in good spirits and in good shape. Which cannot be said about his crate liner: it was ripped apart. Huge holes on both sides and the owner told us that she kept throwing the "white stuff" away as he was digging deeper into the liner. Well, he was on his own in the crate. They let the dogs out four times a day for an hour and the rest of the time they are in the crates. Jake was not used to that but he adapted.
We got back a different dog. He is much less excitable, much steadier I would say; I want to say "he matured". He is much better on his own, pays more attention to the chewing. On the other hand, his training has taken a hit: we need to recover our commands.
On the whole, it was not a bad experience. Since we have no alternative, we have to live with this kennel and as kennel go, it's all right.
