Hello, I am interested in knowing just how much everyone feeds their adult boxer, as well as how much you fed them as a puppy. Also, curious as to what type of food you use? Has anyone used the Royal Canin Boxer Formula? If so, did you like it? That's what I am feeding my dogs right now. I am just interested in knowing if I am feeding my dogs the right amount of food for their needs without having them gain weight. Your advice is appreciated!
