Sure, all it takes is you walking through the door to get your pet's tail wagging, but just picture how much happier they'll be when you come home with a box full of treats for them. That's the concept behind Surprise My Pet, a subscription service that ships monthly packages full of treats and toys for your furry friend.

Each of the 5–7 pet-tested and trainer-approved items in your shipment is chosen based on your dog's size. To ensure quality, Surprise My Pet selects natural and organic treats whenever possible, largely avoiding filler ingredients such as corn and gluten. The boxes incorporate products from several brands, including Aussie Naturals and Blue Dog Bakery.

Pet owners can feel doubly good about their purchases, as 10% of all proceeds are donated to various animal charities.
