Dogs are one of the most popular pets in the world and there’s a reason why – they’re loyal, loving, and make great companions. But there’s a lot more to these furry friends than meets the eye. Here are five interesting facts about dogs that you might not know.
1. Dogs have a phenomenal sense of smell
Dogs have about 300 million scent receptors in their noses, compared to humans who have just six million. This means that they can smell things that we can’t even imagine. Their sense of smell is so acute that they can even detect diseases like cancer.
2. Dogs can understand up to 250 words
While dogs might not be able to speak like humans, they can understand a lot of what we say. The average dog can understand around 250 words, although this number varies depending on the individual dog.
3. Dogs sweat through their paws
Dogs don’t have sweat glands all over their body like humans do. Instead, they sweat through their paws. This is why you might see your dog leave wet paw prints on the floor on a hot day.
