That's awful. I feel your pain. I've had to put a few down and it is always gut wrenching. But, when the time comes, it's the humane thing to do. The wife and I both had dogs growing up, and we had dogs from the time we were married until we had to put or male Golden Retriever down. That was the toughest. That fellow raised our two kids. He was as much a part of the family as any of the rest of us. We were then without a dog for fourteen years. Finally broke down and took on a rescue Beagle mix in August, 2010. The wife thought I had lost my mind, but she has turned out to be very special ... one of the best dogs we've ever had. She's thirteen now, almost blind and losing her hearing. The day is coming and I'm having a rough time dealing with it. We have agreed that we don't think we can do this again. God bless, man.
