The OBBD is larger than the Boston Terrier. The mother is 52 lbs. They have virtually no genetic diseases. The puppies will be low shedding, very active, athletic and playful. Great for active family with children. They will be good with cats if socialized to them early. They want to please and are easy to train but do need basic training. The pups from the litter that I have sold have all been potty trained for awhile so the rest should be easy also.
