Jack is a fun puppy to watch play. He has taken over our cat's toys and loves to carry them around. I'm estimating him to be in the 5.5-6 pound range as an adult. He's the typical Maltese puppy, loves to play-play-play and then crash onto someone's lap for a nap. He will go to his new home with 2 sets of shots, wormings and has been vet examined. APR registration.
