I once had a dog that I raised from a puppy. He was wonderful during his early years, but things changed when he grew into a big 80-pounder at the age of two. One morning, as I was heading out to work dressed in a sweater and winter coat, he jumped onto my bed. I sternly told him "NO" and tried to guide him off, but he unexpectedly bit my arm, piercing through my coat and sweater, and I bled. After consulting with a trainer, we suspected he might have Canine Rage Syndrome. It was heartbreaking, but I had to make the tough decision to put him down for safety reasons. I couldn't bear the thought of rehoming him and risking someone else's safety. That was my last experience with large dogs, and now, I'm more of a cat person!
