Iv always given mine both.Kibble and canned as their food,and human food as treats.Im actually thinking of taking them off of the kibble and replacing it with a home made menu (boiled or steamed).Mine love their treats
I give them carrots,apples,pears,peaches,bananas,strawberries, orange,plum,peas,beans,eggs,buiscuits,cereals,meat (all kinds),cheese,yoghurt,icecream,cream..etc etc,they always get a bite of what ever it is we are eating and they love it
