Are dogs colour blind?

Have you ever wondered whether your dog is colour blind? Well, it was once widely believed that dogs couldn’t see colour, only black and white.

Contrary to this popular myth, recent studies suggest that dogs are not colour blind.

Dogs can see colour, just not as brightly as humans. In fact, studies have found that dogs see in shades of yellow, blue and grey[1].

Did you know that some of the most popular dog toys are red and orange, colours that dogs find hard to see? So if your dog runs straight past the toy that you just chucked, it may be because they’re struggling to notice it![2]


Do dogs feel guilt?

However, research from 2009 has found that dogs don’t feel guilt when they do something wrong. The irresistibly cute look is actually a look of fear at the reaction of their human owner; a learned behaviour[3].


How many dog years are in one human year?

If you’ve ever wondered how old your dog is in human years, don’t bother! The theory that one human year equates to seven dog years is a very traditional way of calculating a dog’s age. It’s based on the (very general) assumption that the average life expectancy of a dog is around 11 years, while that of a human is around 80 years. A dog’s life expectancy actually depends on the breed and health of the dog[4].

There’s a loose correlation between dogs having a cold, wet nose and being healthy. However, if your dog’s nose is warm or dry, it doesn’t always mean that they’re sick.

If your dog’s nose is dry, it could be for a number of reasons. The wetness of a dog’s nose can depend on factors such as the environment they’re in or whether they’ve just woken up. However, if you do notice that your dog has any other symptoms of illness, you should contact the vet[5].

You can’t teach an old dog new tricks

There’s actually no evidence to suggest that older dogs can’t learn new tricks, cues and behaviours. While it’s true that younger dogs (much like children) learn things more quickly than older dogs, this isn’t to say that you should stop training older pooches[6].
