Hi Nate, I would increase his food to 3 cups a day. Most members feed their puppies 1 cup of puppy kibble 3 times a day. Puppies need the extra calories, minerals and vitamins for their growth and development. Once Obi is 7 months to 1 year, you can switch him to an adult formula kibble and reduce his feedings to 1 cup twice a day. I don't have any experience using slow feed bowls, but have seen them, and know people who use them and love them.
