We absolutely adore Alta Vista. We've brought our pup here for both boarding and pupscouts and she loves it. Her first stay was when she was only 3 months old and she is always anxious to go back.
The staff is beyond friendly--they know our pup by name and are always super helpful. The one time our dog got a scratch on her nose from playtime, Dion came out to speak with us and offered salve and a doctor visit if it didn't heal quickly (which it did). The genuine care the staff shows for our dog coupled with her immense excitement to rush in the door every time we go makes leaving her there an easy choice.
If all of this wasn't enough, the price of boarding our dog at Alta Vista is the best I've found for what we get. For only $10/day, she plays for the majority of the day with lots of other dogs--given how exhausted she is when she gets home to us, her having playtime makes me feel much better about sleeping in a crate overnight.
I cannot say enough great things about Alta Vista--if you're looking for a great place to board or exhaust your pup, it's the place to go.
