After much research and reading I put Lilli on Wellness Large Breed Puppy food. At the same time switching my Beagle to Orijen Senior. Following the directions - Lilli gets 4 1/4 cups a day in 3 parts. everything I've read says you don't feed as much with these grain free foods. However, she wants more - she wants to eat the Beagle's Orijen...even prefers it to the Wellness. So, my question saint owners is - how much should I be feeding my little giant? She is 14 weeks and 40 pounds.
