Sienna is a two month old Lab mix with a brindle coat. We think she might have some Boxer or hound in her to give her such beautiful coloring. Sienna is a social butterfly who has never met a dog or a person she did not like. Sienna is an active and playful pup with a sunny disposition. She is a charmer who’s playful antics have won over the hearts of the big dogs in her foster home, and she would make a wonderful playmate for any dog.
