My dog really doesn't like people or animals wearing fluorescent clothing. I thought it was just my dog, but recently, whilst stuck on a motorway at night in the rain, following a crash, a policeman in full day glow overalls stuck his head next to the car and... well, the policeman remarked that it was common for dogs to dislike fluorescent clothing.
So the question that I would like to know is, why this might be?
I know dogs have different colour vision than humans, as represented in the below image:
Initially I was thinking that the fluorescence might appear particularly bright for them, (looking at the bright yellow 'band') and this was what dogs disliked.
But then I saw this image (below) to do with reflectance of fluorescent ink (fluorescence is occurring either end of the human visible spectrum) and it made me think, is it actually possible that rather than making things seem brighter, fluorescent clothing makes things almost disappear to a dog? In such a scenario the dog is scared because they just see bits of objects moving not a complete picture.
