My 13 lb mixed Male, un-uetered one and a half year old pup would LOVE your dog no matter the size! He gets along with everyone! We play fetch every morning before I go to work and every night before we go to bed. If its dark outside we have close in the dark balls for extra fun!! Big back yard with some hills to help tucker them out. I love to snuggle and protect all dogs as if they were my own. Medium - big dogs are not allowed on furniture. Smaller dogs allowed on furniture and bed. Willing to sleep on the floor if the bigger babies need the extra loving! I really don't mind it!! Loving, kind, fully fenced home waiting for your babies visit.
