Get Started

This first step is to complete our online forms (Pet Profile, Owner Agreement, and Emergency Care).

Once you’ve submitted our online forms, you can Bring your dog Monday through Saturday from 9:30 am to 2:30 pm to be evaluated by a knowledgeable, dog-loving staff member. The process takes up to 20 minutes, only costs $20 per dog, and there is no appointment needed. We do not give evaluations on major US holidays, major holiday weekends, or on the days before or after major holidays. Your dog must pass our evaluation to stay for daycare and boarding, however, your dog does not need to pass our evaluation for our grooming services at our Vienna location.

You must present proper/current documentation regarding your dog’s vaccinations at time of evaluation. If a puppy, your dog must complete the initial three rounds of booster vaccinations. It must be a full 48 hours after a shot or booster to be evaluated or attend daycare/boarding. Please be aware that your dog must be older than three months; current on Bordetella, Rabies, and Distemper vaccinations; and spayed or neutered if your dog is older than seven months of age.
