Look at our Frenchton litter! From left to right, say hello to Dove, Wren and Lark. They are 9 months old, 12lbs and came to rescue after their breeder could no longer keep them. Frenchtons are a mix between Frenchies and Boston Terriers, so they will be on average 15-25 lbs when fully grown. These pups are sociable, sweet and fun! Are you prepared to welcome a young pup? They require time, patience and a willingness to make a lifetime commitment.
