Adopted from humane society at about 10 weeks. Was found as a stray at about 6 or 7 weeks. We struggled with separation anxiety and noise phobias. We still have some issues with fireworks but not as bad. Very intelligent and food/ toy motivated. Very reactive to other dogs and humans, especially when I'm around. Severe fear aggression at vet clinic, so he is trained to wear a basket muzzle. Otherwise great with kids and adults.
