That's a difficult question. I've been amazed by my pets and proud of all of them. I'm really trying to think of a single 'proud' moment that stands out above all others, but I honestly can't. Maybe it was when my Solomon barked angrily one night and we let him. The next morning we realized someone had tried to break in through the kitchen window. Way to go, Sol! I never stop my dogs from barking at night like that. He did his protector job very well that night!
