We don't do the raw diet so I'm no help there. I just have to chime in here since we just boarded our boys at Petsmart.
I was NOT happy with them! We had to pay extra for 'play time' and then found out that consisted of ONE day out in the play area with the other dogs there for daycare. So our boys would have been in a kennel (at least they were together) from Thursday-Monday with playtime on Saturday. We ended up cancelling our trip (due to other reasons) and came home Friday. The boys didn't seem to like the place either. Huskies need their daily exercise and this place didn't give them ANY!!
That's just my experience. We've been having a horrible time finding a boarder since we moved to the Seattle area and Petsmart seemed like a good place until we realized the playtime deal. Camp Bow Wow was our place in Colorado Springs and we LOVED it; so did the boys LOL. Each franchise is different though, so I hope you have a better experience.
It's a shame they won't feed your dogs the raw diet. I hope you find a good alternative.
