Go to the Dogs

Have you seen their house lately? It's really gone to the dogs.
It's true that it has become run-down and in serious need of repair, but I'm sure that it can be fixed up to look like new.
I guess with a little carpentry work and some paint it could look pretty decent.

The city schools are going to the dogs

Smell a Rat

How come the front door is open? Didn't you close it before we went shopping?
I'm sure I did. I can't understand it. Frankly, I smell a rat.
Me, too. I'm convinced that something is definitely wrong here. We'd better call the police.
