That I can watch the live video feed, call to check on my dogs, and that the employees are friendly and recognize my dogs. The pens often look overcrowded to me considering there's only one person to watch all those dogs, but since I've never heard of a fight I can't argue with the method.
My dog is happy. Very flexible hours and days for drop off and pick up. Having nice dogs for my dog to play with is a priority. Seems to be kept clean and orderly. And I like the convenience of being able to drop off for daycare any time without a reservation. Takes away a lot of stress and worry when plans change and I need someone reliable to care for my dog.
