Mr. Pen dog carrier backpacks are designed for carrying small and medium dogs; we highly recommend pets less than 12 lbs; the larger dog may bring more weight and uncomfortable feelings for the owner. Mr. Pen dog carrier backpacks is made of breathable mesh and a thick sponge allowing maximum air circulation, so they won't feel too tight or too stuffy.

A hands-free pet carrier can be worn on your front side or your backside if you like. It keeps you closer and increases pet's sense of security when you carry your cat or dog around. Meanwhile, the thickened sponge pad helps to relieve the burden on your shoulder. The adjustable and wide shoulder straps can reduce pressure for you and allow you to carry your pet more closely, while the padded back panel ensures they'll be comfortable too.

This pet carrier backpack is lightweight and portable; you can use it to carry small dogs for biking, hiking, camping, out walking, or meeting friends. It allows owners and their lovely pets to have more adventures together.
