Pet Sling Carrier Guide: How to Choose the Right Size for a Small Dog or Cat

Short answer: a pet sling suits small, calm pets such as toy breeds, puppies and cats. Choose by your pet's length and build, not only weight, pick a breathable fabric, and if your pet is between sizes, go one size up.

When a sling makes sense

  • Short walks, shopping trips and busy sidewalks with a small dog.
  • Keeping a puppy or cat close while you move around the house.
  • Pets that like being held and settle against your body.

A sling is a carry bag for short outings. It is not a car seat, a crash-tested carrier or an airline carrier, so check the rules for your car or airline separately.

What to compare

Feature What to look for
Size Your pet can sit or curl up comfortably, with its head out
Fabric Breathable mesh for warm days
Strap Crossbody, sitting comfortably across your shoulder
Weight Light and foldable, so it fits in a tote

How to measure your pet

  1. Measure from the base of the neck to the base of the tail.
  2. Measure around the widest part of the chest.
  3. Compare with the seller's size guide. Slings often run small, so size up if in doubt.

First outings

  • Let your pet sniff and sit in the sling at home first.
  • Start with short trips and keep a hand on your pet.
  • Use a harness and leash as usual.
