Arlo is definitely a charmer. At just 7 weeks old he knows just how to tug at your heartstrings. Arlo loves to cuddle, but also displays a spunky demeanor when the occasion calls for it. Arlo is a retriever and will most likely be a medium size dog when grown. Someone bobbed his tail and we have no idea why. Arlo is in a foster home with other dogs and loves the attention.
