K9 Sport Sack Urban 3 dog backpack carrier in Leaf, size Medium

A dual-use dog carrier that converts into an everyday backpack, with a padded laptop sleeve and comfort-focused carrier features.

The Urban 3 is designed for people who want one bag that can handle both daily carry and short dog outings. In everyday mode, it works as a regular backpack. When your dog is coming along, it converts into a carrier in an instant.

Made for city use and short trips with your dog

The bag is described as a casual-use dog backpack with a sleek, transformable design. It is intended for dogs with a length of 17 to 19 inches from collar to the base of the tail, which the listing says suits breeds such as Beagle, Cocker Spaniel, Corgi, French Bulldog, Shiba Inu and Scottish Terrier.

Everyday bag mode

For normal carry, you can load your gear and slide a laptop into the padded sleeve before folding over the top to close the bag. That makes it easier to use the Urban 3 as part of an ordinary day in the city, rather than keeping it only for pet transport.

Carrier mode for your dog

When you are ready to carry your pup, the bag converts to a dog backpack. The listing highlights patented arm holes, an angled base, vet-designed cinch straps and ventilated sides, along with a built-in waist strap for a more secure fit during semi-strenuous activities.

Before you choose the Medium size

  • Best suited to dogs measuring 17 to 19 inches from collar to tail base.
  • Listed as a casual-use carrier rather than a specialist hiking pack.
  • Works as both a dog backpack and an everyday backpack.
  • Leaf is the colour shown for this version.

The product details also show this listing as the buy box winner and note that it does not violate MAP.

What to expect

This is a practical two-in-one bag for owners who want a city-friendly backpack that can also carry a compatible dog. The main appeal is the switch between everyday bag mode and carrier mode, rather than a long list of extra features.
