People sometimes wonder if their dog would be happier at home with a pet sitter or boarding in a home or facility when they need to be out of town. The answer depends a lot on the dog and the dog's usual environment.
I have found that older or nervous dogs who live in a quiet adult home, usually do better staying at home and having a professional pet sitter stay with them.
Younger, well-socialized dogs do just fine in a boarding environment. Naturally, I think that in-home boarding is preferred to a kennel. Our boarding dogs become part of our family and after the first day or so, they learn the routine and it seems like they forget that they live somewhere else and thrive in our busy house. If I went out of town and left Cooper at home, he would sit in the den and watch for me until I returned.
Dogs are remarkably adaptive and will do well as long as they are well loved and cared for in your absence. The important thing is that YOU feel comfortable and confident about where they are while you're gone.
