Our dogs have been boarding at Second Home Pet Resorts for the past several years whenever we travel. I have been boarding dogs for years in Phoenix and I can truly say Second Home is far above the rest.
The big positives for us is that they have large suites that they dogs stay in. This is not cages separated by chain link. These have walls and doors. We have two small dogs and get a suite that is large enough that we can put their existing dog crate (which is large dog size) with them. This gives them comfort because they consider it their house.
I also like that there is someone there 24 hours a day and that they will let you arrange for late pick ups. This makes much more convenient to pick up your pet as soon as you get home even if it's a late flight.
My dogs love the cuddle time. The staff is very friendly and understanding. They really seem to get that you are dropping off your family not a family pet.
