Chihuahua Harness
Chihuahuas are classic escape artists, and the SecureFit holds firm. Browse the full Chihuahua harness collection for more options.

If your small dog has ever backed out of a harness, you know how stressful it is. The SecureFit is built to stop that. Its structured, fitted design holds more securely than a loose everyday harness, with multiple adjustment points that let you dial in a close fit on a tiny frame and close off the backward escape route. Yet it stays breathable and comfortable, so security doesn't come at the cost of an airy feel. It's a strong match for Chihuahuas, Yorkies, and Pomeranians, the kind of tiny, narrow-necked breeds most likely to wriggle free. If you've had a heart-stopping moment with a slipped harness, the SecureFit gives you a dependable, held-in fit you can trust on every walk.
Its structured fit and multiple adjustment points let you dial in a close, snug fit that closes off the backward escape route. Dogs slip free when a harness is too loose, so the key is the secure, fitted design. Adjust until two fingers fit snugly underneath, no more, for an escape-resistant hold.
Yes, every SecureFit includes a matching 1.5m pet leash, ready to use straight out of the box. No separate leash purchase needed for everyday walks.
Yes, the SecureFit uses a breathable mesh build. It's more structured and held-in than our lightest everyday models, but it stays airy and comfortable. You get a secure, escape-resistant fit without sacrificing the cool, breathable feel of a mesh harness.
The SecureFit comes in sizes S, M, and L, fitting a chest girth from 30 to 46 cm (12 to 18 in) and dogs from 1.5 to 7.5 kg (3 to 17 lbs). A snug fit matters most for escape prevention, so measure your dog's chest and check the Fit and Sizing menu above.
A snug fit is not the same as a tight one. The SecureFit is adjusted to sit close without restricting movement, so your dog stays comfortable while the design removes the slack that lets dogs slip free.
No harness can guarantee against every escape attempt, but the SecureFit's close, structured fit is specifically designed to remove the slack that lets dogs slip free. For the best result, follow the sizing guide closely and check the fit is snug at the neck and chest.
It takes a bit more care the first time, since getting the snug fit right matters for it to work well. Once you've set the adjustment points for your dog, putting it on for daily walks becomes quick and routine.
