Whenever we've lost a dog, since married, my wife has me dig a hole in the backyard and we bury them back there. I had to do the same for my SIL's dog and my MIL's dog. They didn't have yards at the time. So right now I have 4 dogs (2 are mine) buried back there. (3 boxers, 1 collie.)Plus a bird. And whatever frogs my kids have pulled out of the pool.
Now my SIL has her own yard, so when either of her 2 pass, she can bury them there.
My MIL doesn't. However, she has small dogs now. While I would never get a small dog, nothing smaller than a bulldog which I've never had, but would love, I'm glad she has small ones.
My wife grew up loving boxers, so we'll always have one.
I will never not have a dog in the house.
A) We love them too much and
B) when there's no dog, my wife makes me get up and check the house in the middle of the night every time she hears a noise. Any noise. Even if she's the one who made it.
