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.
NPR published the original interview with author Alexandra Horowitz in October 2016

Kennel cough is a common and highly contagious dog disease. It causes an ongoing, forceful cough in infected dogs and swelling in the lungs, windpipe, and voice box. If your dog has an unrelenting cough that sounds like a honking goose, he may have kennel cough.
While kennel cough sounds horrible, fortunately the majority of dogs recover without treatment. So what exactly is kennel cough in dogs? What dogs are most at risk for kennel cough, and what are its symptoms? Can humans contract kennel cough from their pets? Is there a vaccine for kennel cough?
In this DJANGO Dog Blog article, we explain the causes and symptoms of kennel cough in dogs. We also review available treatment options, discuss the Bordetella vaccine, and provide tips for prevention.
In an increasingly pet friendly world, dog carrier bags allow us to take our four-legged family everywhere. Whether you are about to board an international flight, ride on public transportation, go hiking, or spend the afternoon running errands with your four-legged friend, getting your dog used to a pet carrier is essential.
Is your dog new to pet carriers? Nervous, excited, or jumpy in any type of dog bag or pet purse? It is very common for dogs to be scared of new carriers or even try to jump out, especially if they're not used to being carried. How do you teach your dog to love riding in a bag?
In this DJANGO Dog Blog article, we provide several steps to help your dog get used to a new pet carrier.
