I feed canned with kibble but mainly for him to eat something yummy. He LOVES canned food and he rarely eats dry kibble without it. So I started it to get him to eat properly and on a good schedule.
If he ate his dry kibble happily and normally, I wouldn't worry about wet food.
He literally won't eat for days if I just leave dry food out, lol, and I really don't mind giving him something yummy as it's nice seeing him enjoy his meals.
It does provide added moisture and can sometimes up the protein amount. I feed a bunch of different canned foods but mainly Natural Balance and NV Instinct.
