“The most important first steps you need to take are to check with

The guiding principle of Doggie DayCare/Doggie B&B/Doggie Boarding is
simple - provide a safe and healthy atmosphere with lots of
interaction, both with other dogs and with people. Since dogs are
social animals and enjoy being part of the pack, a social setting with
other dogs is ideal for them. They can gnaw on a favorite toy, hang
out with the humans, or just lounge on a couch and watch TV.

“Today’s daycare centers are cageless, have scheduled activities
(including naptime), and boast playgrounds complete with jungle gyms
and toys to keep dogs entertained. Moreover, they require interviews
and vaccinations - only friendly, healthy dogs are allowed.

The idea behind full-time daycare is that dogs are social animals.
Most important, a happy, pooped pooch won’t need tons of exercise and
attention when its owner gets home.”
