It has been a fantastic purchase and changed everything Review: It’s worth paying for the right product - My little three legged affenpinscher weighs 4kg and other bags just aren’t supportive enough, he just sinks into their depths. This bag allows him to watch where we are going and to relax against the bag (where the zip is). It’s easy to get him in and out and he is so comfortable he falls asleep. The bag has good straps and do we don’t feel his weight when carrying. I’m glad we spent the extra and got this sack. ## Features - DUAL-USE CARRIER - Trendy, sleek, and transformable, the Urban 3 is unlike anything on the market—an ideal, casual-use dog backpack that doubles as a regular pack for you. - FIND THE RIGHT SIZE - The X-Small is best for dogs with a length of 9-12” from collar to the base of the tail.

The sport sack is convenient and easy to use. It has been a fantastic purchase and changed everything ### ⭐⭐⭐⭐⭐ It’s worth paying for the right product *by S***E on 12 March 2024* My little three legged affenpinscher weighs 4kg and other bags just aren’t supportive enough, he just sinks into their depths. This bag allows him to watch where we are going and to relax against the bag (where the zip is). It’s easy to get him in and out and he is so comfortable he falls asleep. The bag has good straps and do we don’t feel his weight when carrying. I’m glad we spent the extra and got this sack. ### ⭐⭐⭐ Go bigger *by A***R on 2 January 2020* I bought one of the packs. I paid the import tax twice on it because I paid the import tax when I bought it on Amazon, and then UPS wouldn't let me have the package until I paid the tax, even though I told them I had paid it. Then when I got the pack home it was too small for my dog even though I went one size bigger to be sure he could fit in it. Really disappointing. ## Frequently Bought Together - K9 Sport Sack | Dog Carrier Adjustable Backpack (Medium, Air 2 - Summer Mint) - PETLESO Dog Goggles Small Breed, UV Protection Dog Sunglasses Medium Breed Dog Goggles for Medium Dog Outdoor Riding Driving, Medium Orange - K9 Sport Sack | Foam Booster Block Dog Backpack Carrier - Booster Block Only, Bag NOT Included (XS/Small) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/56483157-k9-sport-sack-dog-carrier-adjustable-backpack](https://www.desertcart.pl/products/56483157-k9-sport-sack-dog-carrier-adjustable-backpack) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
