For about six months, I took Bea to "Doggie Day Camp" two days a week at the Petsmart Pet Hotel" in Woodinville, WA. I got to know the staff and they got to know Bea. I would have been absolutely comfortable in leaving her in their care. They have "luxury" rooms with TVs and you can buy play time and even doggie ice creams and peanut butter kongs. It's the luxury aspect of it than appeals so much to me. Another doggie daycare that Bo has gone to "play days" at, is lovely too but it's not TVs and Ice Cream.
How about taking him with and staying in a pet friendly hotel?
Bully care exchange is a GREAT idea. If I were in SoCal, I'd take you up on that.
