Review: 👯‍♀️ - Ich und mein Hunde liebt es nun ist auch eine schwierige Wanderung in der Sächsische Schweiz möglich
Review: Puppy loves it! - 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.

## Features

- GIVE YOUR DOG A BOOST - Put the Booster Block in the base of your carrier (sold separately) to help your dog sit 3” taller. Ideal for pet parents who want to purchase one, long-term carrier and let their puppy grow into it.
- WHEN TO USE - This booster block is also useful if your full-grown dog has a wide body but is short in length or is in between carrier sizes.
- 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.
- 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.

### ⭐⭐⭐⭐⭐ Good quality
*by K***T on 7 August 2025*

Fits my pet and he is secure while taking a bike ride. Pup is a chewer , this pack is very durable and stood up to his choppers. Would like it to be a little more stable when trying to put pack on back and taking it off. Have to get lower to a table , counter or something for pet to be stable especially if it fidgets in the process of loading and unloading. My pup feels secure once in and rests paws on my shoulders while putting head in air. It’s nice that I can see him over the shoulder . I thought it would be difficult to get pup in. Once I figured out the process it is not any harder than a harness just as long as pet is calm. There are detailed directions with pictures but they were on cards attached to pack. When I detached it, they fell apart and out of order, hence my need to figure it out.
