Dogs by Jessica bradshaw(age 13)
Dogs are really nice,cute creatures but can also harm you.. Dogs are great – they provide us with love, companionship and are always there when we need them. Their sense of smell is at least 40x better than ours. The area of cells in the brain that detect different smells is around 40 times larger in dogs than humans. This means that your dog can pick up on way more smells than we ever could. This is why dogs are often used to sniff out people, drugs and even money
medical detection dogs are a thing. Because their sense of smell is so great, some dogs can be trained to sniff out medical conditions. They are used to diagnose a particular condition or to alert their owners if they need more medication. Some are even being trained to sniff out Covid-19! Dogs rely a lot on their sense of smell to find food, potential dangers, and friends, so needless to say they sniff a lot. Their noses are designed so smells can stay in their nose while air can move in and out of their lungs at the same time, which means they can breathe freely and still work out what that smell is!
So, not all dogs like water, but the ones that do tend to be pretty good swimmers (but again, not all are so always keep an eye on your dog in case they decide to take a dip out and about).
Newfoundlands are so good in the water that for years they’ve been used as water rescue dogs. In 2016, a brave Newfoundland called Whizz was awarded the PDSA Order of Merit for saving nine people from the sea over his career as a water rescue dog.
Most dogs could easily outrun a human – they’re built to run and chase! The fastest breed of dog by far, though, is the Greyhound. These speedy sight hounds can reach a top speed of 45mph within seconds of starting to run.
While dogs do sweat, don’t expect them to be getting damp armpits any time soon. Where humans sweat watery liquid to cool down, dogs produce a pheromone laden oily substance that us humans can’t detect (dogs know it’s there because of that great sense of smell). The only place that dogs sweat like us is on their paws, so instead they pant to cool down. This is why it’s so important to keep your dog cool on those warmer days to make it easier on them.
