The most common misconception among dog parents is that dogs are colour blind, which in reality, they are not. Your dog can see Blue and Yellow colours, and this is what you need to know when picking a dog toy in a particular colour. Avoid buying red, green, yellow, orange and other colours as dogs tend to see them in brown and often tend to ignore them. Instead, buy fetch toys in blue as they will stand out in contrast to green grass, which looks brown to your dog. As a rule of thumb, vibrant yellow or blue toys are the best when it comes to your dog's colour vision. However, colour is just one aspect to consider while picking a dig toy, and you should also consider factors like squeak ability, texture, and the general smell of the toy.
