I have had goldens for twenty years. This is my sixth one and I am having a terrible time with him. He is one year old and was neutered this morning. Tonight he is howling in his crate. Aren't they supposed to sleep? He has had his pain meds. He has been taken outside. He had a little food. He normally goes into the crate at night begrudgingly but without a fuss. Tonight he growled and snapped. I understand that part--he's cranky from the pain. But the howling is driving me crazy. He has always been a high-energy, hard to handle dog. In fact, I got him from a young guy who is a runner and hiker and couldn't handle him. I seriously have never had a golden, or a mixed breed, or a child that is this difficult. But what I need to know now, is it totally unusual to howl like this after neutering?
