This is actually a small doggie daycare. And at slightly under 4 lbs, Thor was still the smallest one there.
This daycare was leaps and bounds ahead of any other daycare I've seen. There's always at least one certified ASPCA trainer monitoring the dogs at all times. They said they've tried behavior mod, but it's gotten to the point where they are on alert the entire day because they don't know when he's going to snap.
