Here's my pups, doing what they do best: lounging. Harley has developed wrinkles and a bit of gray on his muzzle. His 6th birthday is approaching in about 6 weeks. According to this chart, that's 49 in people years, and that makes him a Senior dog. Now hurry on over to Sweetnick's site to see all the other adorable pups this weekend. They'll be posted by Sunday night.
