Ever wondered why your dog can find a blue ball halfway across the garden, but that bright red one seems to have vanished into thin air? 🤣
Well, there's actually some rather interesting science behind that... and it might make you think twice about the colours you choose when buying toys for your dog. Because whilst we might think that lovely bright red ball is going to be really easy to spot against the green grass, your dog doesn't see those colours in quite the same way we do. And no, before anyone asks, dogs don't just see in black and white!
Dogs have what's called "dichromatic vision", which essentially means they have two types of colour-sensitive cone cells in their eyes, whereas we have three. This means they can distinguish blues and yellows much more readily than reds and greens. Now, that doesn't mean they can't see a red ball. Of course they can! But the colour of that ball doesn't stand out against green grass in the same way it does to us. To your dog, those colours can appear much more similar, making the ball harder to distinguish from its surroundings, particularly when it's sitting still. Add in long grass, shadows, different lighting conditions and a ball that's been well and truly slobbered on (we've all got one of those!), and suddenly finding it isn't necessarily as straightforward as we might think. Your dog may well be relying on movement, scent and other visual cues rather than the colour itself.
And here's something you might not know about Paws Academy... there's a very deliberate reason why the majority of our agility equipment is blue and yellow. It wasn't simply because I liked the colours! When we're working with dogs, particularly when they're learning to navigate equipment, I want to consider how that equipment appears from their perspective, not just ours. Blue and yellow can offer useful colour contrast for dogs, depending on the background and lighting. Of course, colour isn't the only consideration. Contrast, movement, distance and the surrounding environment all play a part in how easily a dog can identify something. But when we're choosing equipment, why wouldn't we take their visual capabilities into account?
It's also worth remembering that colour vision is only one part of how dogs experience the world. Their visual acuity is different from ours, they're particularly sensitive to movement, and their ability to detect things in lower light is generally better than ours. Then, of course, there's that extraordinary sense of smell, which opens up an entirely different way of gathering information about their surroundings. So whilst we're busy admiring all the lovely colours in the park, our dogs are experiencing that same environment in a rather different way. And I think that's fascinating, because it reminds us that what seems obvious to us isn't necessarily obvious to the dog standing beside us.
So, does this mean you need to rush out and replace every red, green or orange toy your dog owns? Absolutely not! If your dog loves their red ball, keep using it. Dogs can learn to recognise and retrieve toys regardless of their colour, and scent, shape, texture and familiarity all contribute. But if you're choosing a new ball for games on grass, a blue one might be worth considering. And if you've ever stood in a field pointing at a bright red ball saying "It's THERE! Right THERE!" whilst your dog looks at you as though you've completely lost the plot... well, perhaps now you've got a slightly better understanding of why!
I've put together this little comparison to show you approximately how some of the colours we see may appear to our dogs. It's an illustration rather than an exact representation of canine vision, but it gives you a really interesting insight into just how differently they experience colour.
Sometimes understanding our dogs means looking at the world a little differently ourselves. 💛
