Cavachon Puppy Blenheim Girl What an absurdly adorable creature our “Cousin Tilly” has turned out to be, she’s chock-full of Cavachon character, droll and silly and perfectly happy to help take about mom’s puppy picture set with complete puppy abandon! She hasn’t a mean bone in her body, she’s cheery and sweet as a puppy can possibly be. A bit of a larger child (about 16 to 18 pounds grown, don’t worry say’s she, I’m just the RIGHT size lol!)
