There are two ways recommend second choice):
1. You just got to touch the 'go out' selection on the menu screen then touch 'shopping' selection. Next touch the 'pet supply' selection. and you will many items to buy for your dog (example. dog food can, water bottle.....).
2. Go take a walk with your pet and go to that shop with the pet supply icon. It is the discount shop. Over there you can find everything in the pet supply there for a minimum price and sometimes you can even find surprise items (I once found a skipping rope !)
You cannot buy things with owner points in Nintendogs. Owner Points are just there for bragging rights-and to unlock new dogs. There is money, which is what is used to buy items.
buy things... espeacially nonreusable items such as water, shampoo, or food. that will lower the money quickly.
