My dog Charlie is medium. Why are harnesses too loose or tight?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered

would you say charlie’s a medium dog? i always have trouble finding a harness because a size small is way to small, but the medium somehow always ends up too loose. (some notes: i’ve measured him and he’s always in the medium size; on the last picture he’s obviously the smaller one ahaha)

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I would say he is a medium-sized dog, yes! Most harnesses will have measurements you can use to help ensure a good fit. I hope this is helpful - Charlie is very cute!
