From poop bags to all-natural treats, we’ve featured a variety of subscription services here on Dog Milk. Each one has something a little bit different to offer (and may be a better fit than others depending on your needs), including PetBox. While PetBox follows the familiar monthly delivery model, it differs from similar services in that it’s the only one that allows you to pick what’s in your box! For those who opt for lengthier subscriptions, this is kinda awesome as it lets you avoid getting the same types of items over and over (you can only go through so many treats in a month, ya know?).

[Disclosure: PetBox sent me a sample box for review. All views and opinions are my own.]

For those who savor the surprise factor of other boxes, don’t dismay! You can also opt for a “surprise me” option if that’s more up your alley. It’s just nice to know that you have the option to choose what’s in your box if you want, though. Also, pet parents who have dogs and cats will be happy to know that you can sign up for a box that includes items for both!

So, what’s in a box? PetBox offers a mixture of high-quality and healthy treats, toys, grooming products, supplements, and more all sized appropriately for your dog (or cat), with plans as low as $29/month. In the box that Wrigley and Smash tried (which was a “surprise me” box), we received: Pumpkin Ginger Barkers from Healthy Dogma, a Beef & Cheddar Slider from TenderStikz, Quickies from The Honest Kitchen, Glow Skin & Coat from In Clover, Peanut Butter & Applesauce treats from Bistro Bites, Omega 3 & 6 Supplement from NoviPet, and a Leather & Jute Pheasant Toy from Aussie Naturals. All in all a pretty decent haul that would have cost a lot more if purchased separately.

In addition to all the goodness that comes in the box, a PetBox subscription also does good outside the box: for every box that ships, PetBox feeds a rescue animal. What does that mean, exactly? They’ve partnered with shelters, rescues, and volunteers to deliver shipments of food every Friday. You can actually follow along every week on Twitter, Instagram, and Facebook with the hashtag #PetBoxFridays. Pretty cool, if you ask me.
