Dogs do see colours, but not as many as we do. They mainly see in the green/yellow spectrum and the colours aren’t as rich or vivid either.
This may be a relief to some who are tired of hearing that dogs hear better, smell better and are faster and stronger than we are!
The bottom line though, is that dogs don’t have full colour vision because they don’t need it. When you toss a yellow tennis ball in the green grass, your dog can find it much easier with their nose than with their eyes.
Dog’s vision is exactly what you would expect from an animal whose life depends on their ability to spot prey. We humans have the ability to see in rich colour and detail, while a dog’s vision is more closely attuned to catching movements.
I hope this helps to clear up any Christmas lunch debates!
