Our rescue Brownie typically gets small doggy kibble, mixed with water to make it easier to chew. He doesn't always like that though and loves to beg for whatever we're eating, so occasionally I'll save him a bite or two from my ham and cheese sandwich.
I've found that when it comes to the kibble food, he's much more likely to eat if we sprinkle just a little bit of shredded cheese in it, then mix it up before putting water in it.
Yes, sometimes he gets canned dog food, to mix things up a bit. I mean think about it for a moment, would you want to eat the same exact thing every single day?
