My Cat and Dog are both grazers

I am wondering if I'm doing anything wrong as I have never had a cat or dog that has left food in the bowl and not simply scarfed down every morsel, and it's something they both do independently.

I tend to just refill the bowls whenever they are empty and they will both just casually graze throughout the day and don't seem in much hurry to finish the bowls.

Is this wrong? They are both a healthy weight and seem very happy.

Thanks!
