Dogs live between 10 and 14 years on average.
Most dogs don’t have very good eyesight. They tend to be near-sighted, meaning that objects in the distance will be blurry.
A dog can hear around three times the range of sounds that most humans can and can hear sounds from further away.
A dog’s paws are made up of fatty tissue. This tissue acts as a barrier from hot or cold temperatures and provides grip on slippery surfaces.
A puppy has baby teeth which will fall out and be replaced by adult teeth as the dog gets older, just like humans.
It has been shown that your dog can feel jealousy when they see you petting or playing with another creature.
Humans have been intensively manipulating dogs’ characteristics through selective breeding over the last few centuries. This has led to the creation of over 300 different dog breeds.
This selective breeding was done to enhance a dog’s abilities or aesthetics (the way they look) and has resulted in many dog breeds having health problems.
