Several months ago I adopted a dog we grew to love — Dulcy (which means sweet). She wasn't a pit bull. After a first examination, my long-time vet told me she was a walking time bomb. Two behaviorists told me I should never let her off leash. One night I was home alone watching a movie, eating pretzels. When I dropped one, Dulcy snagged it. Then she grabbed my arm and bit me. Then she looked at me, curled up her lip, and bit me again. This was a dog I'd had for over two months. When my husband came home I told him what happened, and he said Dulcy had attacked a child riding a bike the week before but he decided not to tell me. I had Dulcy put to sleep. Debby Rahl at BARCS helped me with this awful but correct decision. I felt I'd failed Dulcy. As time went by, I realized that at some point one has to believe there's a happier place for dogs that attack. As much as we'd like to be able to effect change, it's not always possible, and when the safety of others is a consideration, the choice is clear.
