I went through this same thing with my husband when I had Cooper neutered. He knew it was best, but was so worried, even more than me. He called me after I dropped Cooper off and asked me to go get him and call it off. He almost talked me into it too. This is the man who didn't even want a dog. He says he didn't want a dog, because if something happened to them, he wouldn't be able to stand it. We now have two, a boy and a girl, and he really is the hugest worry wart ever!!
