My 20 lb dog gets 1/2 cup (1/4 cup kibble and 1/4 cup topper) twice a day, I add water to the kibble as most dogs don’t drink enough.

Do not free feed. Pick up anything not eaten within 10 minutes, store in the fridg and offer at the next mealtime. They will eat when they are hungry, I wouldn’t worry, unless they don’t eat for 72 hours, as long as they are drinking water.
