A good sling carrier keeps a small dog close, secure, and off your tired arms, so we evaluated these on the things that prevent a bad day out: a reliable safety tether, breathable fabric, and a strap that does not dig into your shoulder. Sizing is the make-or-break factor, since a sling rated for an 8-pound dog will not safely hold a heavier one. In our evaluation we found the best slings combine a secure internal clip, enough ventilation, and a storage pocket for the essentials so you can leave the bigger bag at home. We recommend matching the weight rating to your dog and always using the safety tether, since slings hold dogs that could otherwise leap. For senior or anxious dogs, introduce the carrier gradually and check with your veterinarian if your dog has back, joint, or breathing concerns before regular carrying.
