Hello all fellow boxer lovers!!! I own three boxers. Kaylee is a 3 yr. old fawn, and poor Kaylee suffers from allergies. Currently we are trying to determine which foods. The two newest members of our family are Jake and Bandit, 14 week old fawn boxers. Question. Currently feeding the boxers Purina One Puppy Formula, and I fill their bowls often. However both my babies are under weight. Any suggestions to help fatten them up would greatly be appreciated. They are the loves of my life. Thank you, Forbes.
