From my head on large breed dog food
Simply click on the link in the dog food coupon and you will be directed to the website for that particular vendor. Then, you shop the site for what you need and enter the dog food coupon code in the appropriate place at checkout. If the coupon has no code, the discount will automatically be deducted at checkout. Regardless of whether the coupon has a code, however, you should still check the final total before finalizing the transaction to confirm that the discount has been applied. Some dog food coupons sites sell products directly to you, rather than link you to another vendor site, and provide access to archived dog food coupons if you were not able to take advantage of the discounts in time.
