I am currently having to buy Dog and large breed puppy chow.

Here are some guidelines on how to get a puppy or dog to stop chewing things he shouldn't:

Yes. Another dog or puppy in the home could be a companion and mentor for the puppy. However, if you have a puppy six months old or younger, we would wait before placing a puppy into your home. Puppies close in age often form a strong bond when raised together, making it difficult when you return your puppy for training.
Those puppy teeth can be sharp, but patient, older dogs sometimes have a lot of tolerance.

Different dogs like different kinds of chews, so provide her with a wide variety of chewable items until you find what she likes. Remember that a dog’s need to chew goes far beyond puppyhood, so keep those chew objects handy throughout her life. You can also sponsor a puppy for someone else too –  for any dog loving friend.

SIRIUS® is the original puppy school. Dr. Ian Dunbar created and taught the world's very first puppy class in the San Francisco Bay Area over 30 years ago. SIRIUS Puppy Training Classes literally redefined and revolutionized pet dog training. In fact, SIRIUS created the field of pet dog training. Before SIRIUS, there simply were no family-friendly puppy classes designed for companion dogs, virtually no reward-based classes, and not much fun in dog training... Puppy mills usually house dogs in overcrowded and unsanitary conditions without adequate veterinary care, food, water or socialization. In order to maximize profits, female dogs are bred at every opportunity with little-to-no recovery time between litters. Puppy mill puppies, often as young as eight weeks of age, are sold to pet shops or directly to the public over the Internet, through newspaper ads and at swap meets and flea markets. During the 80's, the SIRIUS Puppy Training video — the all-time best-selling, and the very first dog training video ever produced—helped spread the word about lure/reward, fun and games dog-friendly dog training. In the 90's, SIRIUS was adapted for television and Dogs With Dunbar became the first hit television series since Barbara Woodhouse. The program aired on Discovery Channel in Europe, and then in many countries around the world. SIRIUS established the hallmark for puppy classes and its concept has been adopted and adapted by most educated trainers. All thanks to SIRIUS, puppy classes are now taught all over the world.Because puppy mills focus on profit, dogs are often bred with little regard for genetic quality. Puppy mill puppies are prone to congenital and hereditary conditions including heart disease and blood and respiratory disorders. In addition, puppy mill puppies often arrive in pet stores and in their new homes with diseases or infirmities ranging from parasites to pneumonia. Because puppies are removed from their littermates and mothers at a young age, they also often suffer from fear, anxiety and other behavioral problems. In a puppy mill, dogs are often kept in cages with wire flooring that injures their paws and legs—and it is not unusual for cages to be stacked in columns. When female breeding dogs reach a point of physical depletion and can no longer reproduce, they are often killed. 3. Leave your scent behind. If you are leaving your dog for a longer duration, rolling your dog’s favorite toy or nylon bone between your hands will give him something to remember you by. Avoid making an emotional farewell so that your puppy does not respond with anxiety (i.e., ), which can lead to whining, barking and other destructive behaviors. Many puppy owners have also found that leaving the radio on (with calm, soothing music playing in the background) will help to calm an anxious puppy.
