We have had Sierra since she was 6 months old. She was the last puppy from her litter. She is a very loyal and lovable dog with the right person. We have moved twice in the last 4 years and with each move she hasn't adjusted well. She has separation anxiety and nips when scared. Since the last move she has gone after a couple of our visitors. She is VERY protective of our youngest son who's 3. We have 4 kids and a super busy lifestyle. Unfortunately i think she would be better suited with a different family. I'm heartbroken over this decision but i want what's best for her.
