Visit and Pickup

We are open for visitation and personal pick-up Monday to Saturday 8am to 5pm. A refundable reservation deposit of $450 is required prior to the visitation and personal pick up.

Your puppy will be current on all age appropriate shots when you pick it up. Our puppies get their puppy shots at 6, 9, 12, and 15 weeks of age. Depending on how old your puppy was when you picked it up, you may need to finish it’s shots. The puppy should be given a 5-Way puppy shot, not a 7-Way puppy shot. Please REQUEST that your vet does NOT give your puppy the LEPTO vaccine. The LEPTO vaccine kills more puppies than the actual virus. LEPTO can be given after the puppy is one year old.
