Fergus does daycare about one day a week, for socialization more than anything else. It's hard to meet dogs these days.
We board him and the cats when we go away, they all do fine with being there.
My only problem was one day DH called me at work to tell me he dropped Fergus at doggy daycare and one of the girls took a message for me. I was teased so much over that message. Most people have not heard about doggy daycare.
