i boarded my dogs at one place called country pines and it sucked..they kept them in crates and only took them out on small leashes 3 times a day
so i found a great place called lucky dog lodge

www.luckydoglodge.com

and it was great! the dogs are kept in spacious "rooms" and let out in a fenced area for potty and play time and they are brushed daily.

honestly if you find a reputable place i wouldn't be too worried about it, as long as you know they are in good hands
