Review: Good quality - 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.
Review: Consider this product - There’s nothing to dislike. It’s about 3” thick lightweight sturdy foam. It’s easy to install-just pop it into the bottom and you’re ready to go. Yes it’s just foam but the convenience and the price is worth it because I Don’t want to purchase more than I need. It was made to exactly fit for your Sports Sack. I originally purchased my sports sack for my one dog until I rescued another one. She’s the type that has short bursts of energy and then she’s spent so taking her out on three mile walks was not something she could do. I found this foam and it is perfect for my new little low rider so that she can get that little boost and be able to see above my shoulders. I love that it doesn’t add any more weight but still firm enough that is comfortable for her to stand or sit on for the walk.

## Features

### ⭐⭐⭐⭐⭐ worked for me
*by B***O on October 15, 2022*

I have had a medium K9 Sport Sack for several years for an older dog and it has worked well, held together. I got the one that supports 40lbs, the "Plus 2". Then a smaller dog hurt his leg, and it will probably be a permanent issue, so I bought a small pack of the same model. He is in the low range for that pack. It worked, but his head did not ride high, and his arms did not stay well in the slots. So I got this booster, and the adjustment does the trick, his head is higher, and he rests his arms on my shoulders, and they stay put. I think he likes his head being higher, so he can see well, and resting his arms on my shoulders gives him a more comfortable ride.
