Hi Frankie-
I always add toppers to my dogs’ kibble meals. I do measure everything. If you are using a topper such as canned, which probably is already complete and balanced, you can feed whatever ratio you want and it will be balanced. You should keep unbalanced ingredients less than 25% of their diet. That could be over a week’s time, not necessarily every meal.
I do go by calories. I figured out using the dog food calculator on this site to compute total calories I should feed. I add about 100 calories of topper per meal and subtract 100 calories of kibble per meal. I have two very large lab mix males. I’ve had to lower the total number of calories at times due to inactivity, neutering and age every now and then. I usually just decrease the kibble, not the toppers when I do this. Luckily, most food lists the calories on the bag or can.
They get 1/4 of a can each in their morning meals and fresh, frozen or canned in their afternoon meals.
Hope this helps!
