Penny is 3 years old and 56 lbs. She is super sweet. She is heart worm treated. Penny is house-trained and crate-trained. She's good with adult dogs. Best with a house with no puppies because Penny plays hard and will be too rough for the puppies. All of our dogs are microchipped, spayed/neutered, heartworm tested (and treated if positive) and current on all vaccinations.
