I’m also trying to get my slightly chubby Chihuahua to lose a bit. She gets two meal a day. Breakfast being just 1/8 of a hard boiled egg. Very hard to figure out how much to feed Boss since the food is pretty significant calorie difference. How about alternating each day? This way you can give less of the Perfectus per cup on those days since higher in calories.
I notice with my little chihuahua that giving her breakfast, which is for her 1/8 of a hard boiled egg, cuts her hunger for giving all the calories for dinner. So if you can give dinner a little earlier and wait an hour and give her some exercise with a walk the calories can burn off? String beans in-between instead of caloric treats also helps for the weight lose.
Hope this helps.
