Why do dogs sniff?

Browse → Animals → Pets

Sometimes it may seem like dogs like to stick their noses in everything! The main reason dogs sniff is to learn. When a dog sticks his nose out and takes in a big whiff, he is gathering information! Believe it or not, simple sniffing can help dogs do everything from identifying people and other animals, to recognizing foods, to finding out about where something has been! A dog’s sense of smell is so strong that they can use it to find things that are hidden which no one else can find!  

Can you imagine relying so strongly on your nose? A dog’s sense of smell is believed to be 40-50 times stronger than a person’s. Some experts have even shown that dogs are able to use their noses to pick up on emotions and feelings!
