Brianne is a 12 week old adorable big puppy! She is a lab/terrier mix who is super affectionate, very athletic, and a relatively calm puppy. She is very good using the bathroom away from living space, which is great for a puppy so young! Her mom is a terrier mix who is about 20 lbs, so our guess is that she will be around 35 lbs (?). Brienne is an escape artist and an expert climber and will be able to scale chain link fences. Her adoptive family will have to have either concrete or brick walls, a coyote roller on top of their fences, or lining on all fences which prevents climbing. She can climb any height and has zero fear. Adorable little adventurer!
