The Plus 2 is a backpack dog carrier with a multi-functional storage pack. The storage pack is great for bringing gear, treats, or other necessities along on your adventures. It also acts as a support for your dog's back, pulling your pup in snuggly against your back. Available in sizes S-L, its thicker shoulder straps and padded back panel allow for more weight and strenuous activities. The Plus 2 is our most complete carrier for small to medium sized dogs and fits dog owners small to large in build.
Sizing
Further sizing guidance can be found in the sizing images. If your dog is in-between sizes, we would highly recommend basing your size off the length measurement, as this is most important when fitting a K9 Sport Sack.

The time limit is determined by your climate and activity, however on average we recommend that the dog not stay in the bag for any more than 45 minutes at a time. For hotter climates this number should decrease proportionally.
