People food is food made by people, over processed junk food. Also don't feed your dogs garbage/table scrapes. If you wont eat it it's not really good for them either.

What do they make dog food out of if not food? Meat veggies so on.

Just avoid the bad guys like onions, grapes, and chocolate.

But as treats if you want to feed a fully home made diet study up on it a bit first.
