That is really sad about your dog getting hit. As far as bonding with another dog, people say they do. I had a dog die at 6 months due to hip dysplasia (she had to be put down) and I did have trouble, at first, when we got another dog a year later. But now, after having her a year, I can't imagine how close the bond is. In my opinion people will understand and empathize. How many times does one spouse not be as careful as the other one wants them to be? You didn't think anything was going to happen. Your wife knows that you loved that dog. I'm very sorry for your loss. Therese
