here are some other helpful tips for taking care of dogs. (copied from websites)
Basic Feeding Guide for Puppies and Adult Dogs[1] The first ingredient in your dog's food should be a specified "meat". Not a meat by-product, but the real thing. Puppies and adult dogs were not meant to eat corn and wheat. If the first ingredient in your dog food is a corn, wheat, meat-by-product, bone meal or anything but a real specified type of meat steer clear. By-products are the left-overs, such as the eyes, hooves, skin, feathers and feet that are not good for human consumption (unless the dog food specifically states otherwise.) Beware of ingredients that do not list exactly what it is, such as words like, "animal" and "meat" as opposed to "chicken", "beef", "duck", etc.. See Rendered products in dog food.
A dog should never be punished for deeds you do not like, but rather corrected. What's the difference between a punishment and a correction? A correction is when you give a command of disapproval at the moment the deed is about to be done or is being done. A punishment is anything thereafter.
