Are yellow dog accessories code for 'this dog needs space' (or 'reactive' etc)? If you saw a dog in a yellow harness would you avoid it?
I'm about to order a harness and like the fluorescent yellow one best because it will be the most visible in low light/the dark. The field we will use a lot for walks has a bike path going through it (when I ride my bike through it at dusk I'm so glad when dogs are easy to see). I suppose there are other (possibly better) ways to make them bright though, like lights, if yellow has an established role.
