Hi Haleybop,
In regards to adding an unbalanced topper ( lean meat) to a balanced kibble, veterinary nutritionists recommend to limit unbalanced foods to 10% of the total caloric intake.
For example, if your dog needs 400 calories to maintain weight, you would feed 360 calories as kibble, and 40 calories from an unbalanced addition.
I think feeding twice a day is for our convenience. More often is fine. Some people leave the food available all the time and the dog grazes throughout the day. I’ve never seen it reported that this causes any type of adverse effects on health.
Don’t feel guilty for not feeding raw. After thoroughly looking at that issue from multiple angles I concluded that it wasn’t in the best interest of my dogs and family.
