Cats have better memories than dogs. Tests conducted by the University of Michigan concluded that while a dogs memory lasts no more than 5 minutes, a cat’s can last as long as 16 hours - exceeding even that of monkeys and orangutans.

Cats have more than one hundred vocal sounds, while dogs only have about ten.

Dogs are mentioned 14 times in the Bible.

Dogs can hear sounds that are too faint for us to hear, and also can hear noises at a much higher frequency than we can. Their hearing is so good that they probably rely more on sound than on sight to navigate their world.

Dogs’ eyes have large pupils and a wide field of vision, making them really good at following moving objects. Dogs also see well in fairly low light.
There are 701 types of pure breed dogs.
