How old is he/she? Raw diet is ultimately the best but there are a bunch of great dog kibble out there. I personally use Origen but I've heard Taste of the Wild, Natures Logic, and Victor are all great brands. You'll hear BARF diet thrown out there too (biologically appropriate raw food diet). It's up to you and what your dog will like. If you are interested in bulking, some popular supplements are Dyne and BullyMax for weight gain. Just do some research and see which ones you wanna try. It's a lot of experimentationWhats up guys Im new to the forum and have a quick question. I just purchased my first American Bully and was wondering what you guys feel would be the best puppy chow to start my new guy on in order to establish a good base weight?
