DOGS ARE NOT COLORBLIND

It is a common myth that dogs can only see in black and white, but they can see colours - just not as vividly as humans. They only have two cones in their eyes to detect colours, whereas humans have three. That means dogs see colours on a blue and yellow scale but cannot distinguish between red and green. On the other hand, they have better night vision than humans. This explains why your dog might sometimes lose track of their red ball in the grass. So, think about what colour ball you purchase, they will see a blue one much easier!


OLD DOGSCAN LEARN NEW TRICKS

With patience and understanding you can teach an old dog new tricks depending on what you are trying to teach the dog? or unteach the dog, which is usually more difficult. Like humans, dogs can learn at any age ? it is just old habits that are hard to break!


DOGS ONLY HAVE SWEAT GLANDS IN THEIR PAWS

Dogs have sweat glands only on their paws, not the rest of their bodies. Since they do not use sweat to cool off, dogs have developed another way: They ventilate and exchange heat through panting.

THE OLDEST DOG LIVED TO BE 29

Recorded in the Guinness Book of World Records, the oldest dog ever was an Australian Cattle Dog named Bluey. He lived to be 29 years and 5 months old from the years 1910 to 1939. Bluey lived in Victoria, Australia with his owner Les Hall and worked among his sheep and cattle.


A MOUTH FULL OF TEETH

At 4-8 weeks of age a puppies will get 28 baby teeth. At 4-7 months of age the baby teeth will fall out and be replaced will 42 permanent teeth.


3RD EYELID FOR PROTECTION

Dogs have 3 eyelids - an upper and lower eyelid and a 3rd one hidden between them. It helps protect their eyes from dirt and dust. You will see this 3rd eyelid come across as they are falling asleep.


A DOG'S NOSE IS ITS FINGERPRINT

Dog noses have unique patterns that can serve to identify them, similar to human fingerprints. Also, the wetness of a dog's nose is a sign of good health and helps them in gathering scents.


IT IS WHAT COLOUR??

The Chow Chow and Chinese Sharpei breeds are the only two with black tongues. Nearly every other breed has a pink tongue.

HAPPY TIMES

Stroking dogs and gazing into their eyes releases the 'feel good' hormone oxytocin, and lower blood pressure for both people and dogs. It also helps us both live longer!!


DOGS DREAM JUST LIKE YOU

This will not come as a huge surprise to anyone who has watched their own dog twitching or whimpering in their sleep. Dogs have the same brain wave patterns while they are asleep as humans, so they dream just like we do. But what is more surprising is the fact that not all dogs dream the same amount. Small dogs have more dreams than big dogs.


RIGHT-PAWED OR LEFT-PAWED?

About 90% of humans are right-handed, with most of the rest left-handed and a very small percentage ambidextrous. But dogs are more evenly split, with one third right-pawed, one third left-pawed and the rest without preference. Dogs who are right-footed are more likely to pass the Guide Dog Training Programme than south paws. Research shows right-handed animals tend to be bolder and more inquisitive so are more suited to being a guide dog. Left-handed dogs also tend to be more aggressive.
