Dogs have a sense of smell that is up to 100,000 times stronger than ours! This means that they can detect scents that we can't even imagine.
Dogs have wet noses because they help them to smell better. The moisture on their noses helps to trap scent molecules, which then travel to the olfactory receptors in their noses.
Dogs don't have sweat glands all over their bodies like we do. Instead, they sweat through the pads of their paws. This helps to keep them cool and prevents their paws from overheating.
Dogs wag their tails for different reasons, including happiness, excitement, and submission. The speed and intensity of the wagging can also indicate the dog's emotional state.

Dogs are incredibly intelligent animals and can be trained to do all sorts of amazing things, such as assisting people with disabilities, detecting drugs and explosives, and performing tricks in circuses.
Playing is an important part of a dog's life. It helps them to stay mentally and physically stimulated, and it's also a great way to bond with their owners.
