Reddit mentions of Cadet Sterile Natural Bone for Dogs, 7 to 9-Inch, White

• Lupine collars and leashes - they have a great guarantee of free replacement if the dog chews up the collar or leash. Perfect for puppies. You can find them in most specialty pet shops.
  
  
• Kibble Nibble - this is an interactive toy that I recommend feeding your puppy and grown up dog from. It keeps them busy and they have to work for their food.
  
  
• Nylabones - start with the puppy ones and when your pup starts getting adult teeth move on to the regular versions. Rotate teething toys so your pup always has something interesting to chew on.
  
  
• Sterilized Bones
  
  When you buy Kongs make sure you get the large or x-large size. Don't fall into the marketing scheme where you buy as they grow. Large Kongs are great because you can stuff all sorts of things in it to keep them busy.

  If you have an Amazon Prime account I'd order a lot from them. Free shipping saves you a lot. If you don't have Amazon Prime then you should look at ordering from a bulk pet supply place like Pet Edge. You have to order $60 worth of stuff to avoid the surcharge but you can get some good deals depending on how expensive shipping is. I try to split an order with a friend to keep costs down.

Looks like a typical shin bone. You can get them at the grocery store, butchers, pet store, etc. They're a pretty popular pastime for dogs, and it doesn't really matter the brand -- its appeal to the dog is that it's part of an animal, and it's the same thing no matter what company produces them.

I'm in a similar boat (except I've got more advance notice) and have been finding the Digital Dog Training Textbook linked-to in the sidebar to be invaluable. Highly recommend. It's a little oddly laid out and it repeats itself itself but—as it says—you're really training yourself how to train the pup, so the reinforcement works (at least for me).

Their shopping list (oddly-formatted, watch out) includes:

• At least six chewtoys to stuff with kibble and treats (The Kong Company’s Kong and Biscuit Ball, Premier’s Squirrel Dude and Football, and sterilized long bones^† are the best.)
  
• Water bowl (Only buy your pup a food bowl once he is socialized, well-trained, and has impeccable household manners.)
  
• Dog food (dry kibble) During his first weeks at home, make sure your puppy receives all food stuffed in chewtoys, or handfed as rewards for socialization and training.
  
• Freeze-dried liver for men, strangers, and children to win your puppy's confidence and as rewards for housetraining

  Also, I saw this recommended somewhere. I have used a similar product for our cats and it's fucking magic, so if you're concerned your pup might be stressed, I highly recommend.
