The IN . LINE No-Pull Harness is carefully designed to work only when it fits your dog correctly. For comfort, control, and proper function, a snug fit around the torso is essential — just like the image to the right shows.

If your dog doesn’t fall within our sizing range, we recommend not purchasing at this time — a poor fit means the harness won’t work as intended.

Not sure or between sizes? Send us your dog’s measurements — we’re happy to help you find the best fit. And if your pup doesn’t match our current size options, let us know — we’re working on expanding the range.
