Sorry for your loss. I've been there a couple of times, and it's tough.
I was watching your video sitting in my truck today after lunch, smiling and chuckling, and I looked over and some lady in the car next to me was giving me the funniest look.
I'm sorry for your loss. We said goodbye to two of our puppies this year, both were 15 years old, and just like what you're saying the lack of noise when you come home is so strange.
