My boxer boy is 12 weeks old and eats 3 times a day. How much should he be eating? The bag says up to 1 1/4 cup a day but he scarfs it down the minute he gets it. I have both of my dogs on Wellness and they love it! I've been feeding him closer to 2 1/2 cups a day plus a few puppy treats while training. He's very active outside and has seemed to put on a little weight since I increased his meals. Last week at the vet he weighed 22 lbs which the vet said was good. He just seems so hungry all the time and I have a hard time saying no more when he gives me that 'look'. Any help is appreciated!
