Super sniffer

Don’t even try to hide treats from your dog. His nose knows you have them. Just don’t let him get his paws on any foods dogs can’t eat. Dogs’ sense of smell is 10,000 to 100,000 times more sensitive than that of humans. Just how powerful is that? As James Walker, former director of the Sensory Research Institute at Florida State University, told PBS, “If you make the analogy to vision, what you and I can see at a third of a mile, a dog could see more than 3,000 miles away and still see as well.”
Internal storm tracker

There are some weather myths you shouldn’t believe, like lightning never strikes the same place twice. But here’s one you should never doubt: Dogs can sense when bad weather is coming. Researchers don’t have an exact explanation – maybe your pet actually is a superhero! – but they have some theories. Dogs are sensitive to drops in barometric pressure that come with severe storms, and they can hear low frequencies that humans can’t, like far-off thunder and earthquake rumbles. You shouldn’t solely rely on your pet over meteorologists, but don’t let their weird behaviour go unnoticed. It could save your life.
Secret tail code

As if having an extra extremity wasn’t cool to begin with, dogs can also use their tails to communicate. They lower their tails when they feel scared or nervous. When they’re alert or aroused, the tails wag higher. If a pooch is aggressive or feeling threatened, that tail will stick straight up in the air. Plus, dogs can tell how other canines are feeling based on what direction they wag in. Italian researchers discovered that dogs became more anxious when they saw others wag their tails to the left, as opposed to the right side or not at all. Previous studies showed that left-leaning tail wagging was a result of a dog having a negative experience, like facing a nasty dog.
