When we had just the 2 dachshunds, we used to free-feed:just left the food down and the dogs regulated themselves. Then we brought Murray home.Hansel panicked and went into some kind of 'food competition mode'- he would rush the food bowls and consume all the dachshund food plus Murray's puppy food. He porked up to 24 pounds from his ideal weight of 17 in about 2 weeks. So, we started feeding all the dogs twice a day in separate locations. Food that was not consumed was removed. By increasing Hansel's walks and controlling his food, he was back in good form in no time!So that would be my suggestion- good luck!
