For drop in visits, any dog is fine. Big, small, young or old. I'm not picky for visits, I love them all. For boarding dogs, I prefer older, small dogs. No puppies. I have a large, fenced, back yard. I do have a liner pool so dogs who love water, would not be a good fit. Dogs can stay indoors or outdoors but will sleep inside. My own dog is small, her name is Fritter. I am available so your loved one won't get separation anxiety. We can walk, play fetch, hike etc.. Dogs can ride in my car if they have appts., Please bring their food, bed, leash toy or blanket. I will only board one dog at a time, so they will get plenty of attention from my husband and I. I look forward to meeting you and your dog.
