Mary Kate is a 5 month old BC who currently is about 30-35 pounds. We expect her to get between 40-45 pounds. She is doing great with crate and house training. She plays well with different size dogs. She can be vocal sometimes so may not be good for apartment living. She's a very sweet girl and not overly mouthy. She's learning to follow other dogs in ball play and starting to figure out the routine and what's expected of her. She still occasionally jumps up on people but is starting to understand feet on the ground gets attention. Will require a secure fenced yard.
