Dogs see colours on a blue and yellow scale but they cannot distinguish between red and green.
Dogs are domesticated mammals. They are not naturally wild. Originally, dogs were bred from wolves. They have been bred by humans for a long time and were the first animals ever to be domesticated.
Here are some weird facts you probably didn’t know about dogs
1The “smell” center of a dog’s brain is 40 times larger than that of humans
It is true that dogs can smell thousands of times better than humans. Their noses have millions of scent receptors, for example, a human nose averages 5 million while a Dachshund’s has 125 million; making them useful in sniffing out drugs, dead bodies, bed bugs, explosives, and more.
