Stay dogs tend to dumpster dive more than cats do.

That's essentially how they think the first wolves started to be domesticated into dogs was eating human trash.

They'll still hunt if they have to for survival though.

We have big dumb native threatened birbs where I live, and whenever 1 dog gets out they just go around slaughtering them cartoonishly. To the point where even normal people with jobs (conservationists aside) put signs up asking everyone to leash them. Luckily, people here are good with leashing dogs for the most part
