Dogs are dichromatic — they see the world in roughly two colours: yellow and blue. Red looks dark grey. Orange looks muddy brown. Green and red blur into the same shade. So that adorable pink octopus left on the carpet for an anxious dog to find while their owner is at work? It isn't being ignored. It's camouflaged against the floor.
The IndestructiPaws is yellow and blue for exactly that reason — not because it looks nice on Instagram, but because those are the two colours that pop in a dog's visual field like a fluorescent jacket on a building site. Anxious dogs lock onto it the second the front door clicks shut, because it's the only thing in the room they can actually see clearly.
That's not a marketing claim. That's canine biology — and almost no other UK toy brand has bothered to design around it.
