Review: Ich und mein Hunde liebt es nun ist auch eine schwierige Wanderung in der Sächsische Schweiz möglich
Review: $35 duty into Canada. Haven't used it yet, still desensitizing dogs to it. Looks like great quality. I have 26 & 31 lb Boston Terriers. This is for emergency while on hike & when older one is completely blind & might need to sometimes be packed around. Got1 booster block, need another for little guy but glad I went with medium not small.

## Features

- GIVE YOUR DOG A BOOST - Is your dog still growing? The Booster Block allows pet owners to purchase their long-term carrier without sacrificing functionality during the early years. Put the block in the base of the carrier to help them sit 3” taller.
- WHAT’S INCLUDED - All carriers must be purchased separately. The booster block comes with a removable, washable cloth cover.
- COMPATIBILITY - The XS/S booster size is best for extra small, small & medium carriers. Consider the following dog carriers: Trainer, Air 2, Urban 3, Plus 2, Knavigate, Walk-On, and Karry-On.
- HIGH QUALITY - This block is made of high-quality foam.
- NEED MORE LIFT? - If your puppy is still “too short” for your long-term carrier choice, consider purchasing two blocks. This will provide a total of 6 inches of lift.

We love this backpack; excellent quality. Getting puppy in requires some practice but he enjoys it so much so now gets excited to get in. We get so many reactions and smiles from people around!!! And my 4 month old absolutely loves going for bicycle rides or just being in it overall; helps with taking him to places where normally dogs aren’t allowed, like grocery stores.
