As if we didn’t need another reason to confirm dogs are the coolest creatures on earth, we now learn that dogs can detect cancer and tell time with their nose.
Alexandra Horowitz, canine cognition expert, explains the power and complexity of dogs’ olfactory senses in her new book, Being a Dog.
Dogs obviously have a much stronger sense of smell than us humans - this is why our canine companions are used to sniff out drugs and explosives, among other things. But did you know many dogs can detect melanoma (skin cancer) cells on their owner?
As Horowitz confirmed in an NPR interview, “there's been a budding research program in training dogs to detect various cancers on the breath, in urine, in blood and on the skin. Most of these programs report very high levels of success.”
Why is the canine sense of smell so much more powerful than ours? Biology.
Dogs “possess up to 300 million olfactory receptors in their noses, compared to about six million in us,” Peter Tyson from PBS explains, “and the part of a dog's brain that is devoted to analyzing smells is, proportionally speaking, 40 times greater than ours.”
Dogs can also tell time with their noses. Yes, you read that correctly.
Not only can dogs differentiated between a new and old odor, dogs actually analyze the scent of the air to determine what time of day it is.
“If we were able to visualize the movement of air through the day,” says Horowitz, “what we're really visualizing is the movement of odor through the day.” Dogs detect the movement of odor throughout the day and simultaneously determine time. This also explains why dogs sometimes reach strangely when a storm is approaching. Unlike us humans, they see the storm coming from a mile away.

In June 2016, Mike and I (Steph) packed up our tiny New York City apartment and put almost everything we owned into storage. We flew to the Pacific Northwest with two suitcases and our long-haired dachshund, Django. Over the next 10 months, Mike and I worked remotely, lived in both Oregon and Southern California, and spent almost all of our free time adventuring, hiking, and camping with Django. One of our all-time favorite dog-friendly adventures was a road trip down California's Pacific Coast Highway.
In this DJANGO Dog Blog article, we highlight the best dog-friendly places to visit along the Pacific Coast Highway. Although the PCH technically ends just north of San Diego, we include our favorite pet-friendly beaches, parks, camping grounds, and vineyards to visit on your next road trip from San Francisco to San Diego. We also include an interactive Google Map highlighting each dog-friendly attraction along the route.
Heartworm disease is one of the most serious and potentially lethal canine diseases. It is prevalent throughout the United States and found all over the world. Heartworms are silent killers that can damage your dog’s heart, lungs, liver, and kidneys if left untreated.
If you are a dog owner, you are likely well aware that it is important to protect your dog against heartworm disease. You probably give your dog regular heartworm prevention medicine to ensure your four-legged friend's health and wellbeing. But have you ever stopped to wonder what exactly heartworm disease in dogs is? What causes heartworm disease, and how do dogs contract heartworms? What are the symptoms of canine heartworm disease? Can the disease be successfully treated?
Here is everything you need to know about the causes, symptoms, treatment, and prevention of heartworm disease in dogs.
When we brought Django home in 2015, he had 28 razor sharp puppy teeth. Like a human baby, Django explored the world by putting objects into his mouth. Although we (Mike and Steph) always tried to direct Django's chewing energy towards puppy-safe chew toys, Django would put things in his mouth and chew on items he wasn't supposed to. Since Mike and I were a part of his world, he inevitably started nipping and biting our fingers, hands, and toes.
While mouthing is completely normal during puppyhood, it is important to let your puppy know what is and what is NOT allowed to be chewed on. Why do puppies gnaw on everything? How do you keep your dog from biting you? Are there outdated training techniques you should avoid? When should you seek professional help for your four-legged friend?
We spoke to Denise Harmon, the founder of Brooklyn-based dog training and consultant company Empire of the Dog, for tips on preventing puppy nipping and biting. Here is everything you need to know.
