Yes, my Shiz Tzu is 8 years old and pees in the house, only
at night when I'm sleeping.

First things first - a vet check to rule out infections which
may make the dog thinks that he needs to pee.

Other than that, any major changes in your household or has he
always had this behaviour? Is he neutered? Does he have a
name?

I'm not gonna tie him up at night but I can leave him in
the garage, but, he has to stay in the garage all day while
I'm at work, I hate to leave him in the there at night
too!

Why does he have to stay in the garage all day?
