Why the experts say you should let your dog sniff whatever they want on walks

Why do dogs sniff everything? If you haven’t already heard, a dog’s sense of smell is 10,000 to 100,000 times more powerful than ours. Just as humans use their eyes to see and understand the world, experts say dogs use their nose to “see” the world. In fact, our dogs’ world revolves around smell so strongly, allowing them to sniff actually lowers anxiety and increases their mental health.

So, while it can be frustrating to walk around the neighborhood with a furry companion who tries to stop every few feet to investigate something new with his nose, experts say you should allow your dog to explore on walks. Here’s more….

Why do dogs sniff everything and why is it important?

When we limit our dog’s sniffing options, their daily welfare and enjoyment of the world suffers, Ali Smith, founder at Rebarkable, tells us. As a result, this affects their socialization, behavior, and training as well as their happiness and well-being.

“Allowing our dogs to sniff actually helps create pathways in their brains,” she says. “It relaxes them and allows them to be a dog. This is why sniffing is massively important for our woofs, and why we should always make time.”

Use the 70/30 rule

But how much time is enough time? After all, most of us have schedules to keep and can’t always wait for Fido to finish every investigation. Colleen Demling-Riler, an in-house dog behaviorist expert for Dogtopia, recommends keeping your pup walking for 70% of the time and giving him the remaining 30% to sniff and explore the environment.

“Sniffing is fine, but within reason,” she says. “Walks have many purposes, but the main one is exercise. If you go on a 30-minute walk but your dog’s nose is so active that you barely make it around the block, you will return home with a pup that has lots of excessive energy. This means your dog will likely demonstrate problematic behaviors such as excessive jumping, counter surfing, barking, and/or chewing.”

And nobody wants a counter surfer. So, to make sure you get in a fair share of sniffing and exercise, identify a few of your dog’s favorite places to sniff, then practice walking between those smelly sites without stopping. Practice the “leave it” command, too, so you can explore new routes using the same 70/30 rule with ease.

Include some safeguards

Of course, always watch what your dog is sniffing. It’s OK to say “no” to a smell that is potentially dangerous or harmful to your dog’s health.

Lung infections such as aspergillosis, cryptococcosis, and blastomycosis are common diseases caused by fungi in the soil and other environments. While they are less common than bacterial or viral infections, they are still quite serious. Call your veterinarian immediately if your dog becomes lethargic or develops a cough, bloody discharge, fever, or loss of appetite, especially after an intense sniffing session.

“Always make sure your dog is up to date with vaccinations, make sure they are not licking or eating things they are sniffing at, and try to prevent them from digging in their environment to help control certain fungal infections,” Dr. Antje Joslin, an in-house veterinarian expert for Dogtopia, says.

Appreciate the superpower

When you stop and think about it, a dog’s sense of smell is pretty amazing. The 300 million olfactory receptors they possess, compared with 6 million in a human, can be used for more than just finding their food bowl at dinnertime.

“We know that a dog’s nose allows them to do some pretty powerful jobs — from medical alert dogs to detection dogs,” Caroline Wilkinson, founder of Barket Place, says. “Dogs have been found to be able to sniff out — and indicate the presence of — dangers or diseases, including drugs, bombs, cancers, and malaria.”

Wilkinson says a number of scientific studies conducted over the past few years have explored the effect of scent and its ability to lower levels of cortisol (the stress hormone) in our dogs. Encouraging our dogs to engage in activities that lower stress, such as sniffing new scents, following trails, or playing nose games, can have a positive impact on their welfare. So, the next time you reach for the leash, ask yourself if you’ve allotted enough time for your dog to do some serious sniffing. It may take a few extra minutes, but considering the health benefits it provides, it’s well worth the effort.

Fleas and ticks are common issues with dogs, but they aren't harmless. These pests attach themselves to a dogs' body, feed off their blood, and make them extremely uncomfortable, if not ill. It can be a miserable experience — for both you and your pet. Left undetected, fleas and ticks can transmit a host of unsavory diseases. You need to keep a close eye out for the signs your dog has ticks.

So, where does a dog pick up these nasty critters, anyway? And if they do, how will you know? We’ve got the answers plus a few tricks on how to prevent them (and why this matters). These are the sign your dog has ticks or fleas.

Video: This family dog is the world’s best babysitter

If you think family dogs don't make good babysitters, think again. While it's true a lot of pets encourage mischief, sometimes a particularly sweet animal will be perfect for the role of human watching. This adorable beastie has his child minding duties down to a science, as seen in the latest TikTok video in which a happy golden retriever follows around his little girl bestie as she plays through her day. It's called "Who needs a babysitter?" and proves that our buds are up to the task. (Okay, so you shouldn't actually leave your dog in charge of your child — but there are definitely pups out there who make perfect companions for kids.)

"Dogs can't be babysitters," reads the first title in this funny dog video. We see our golden star with his small child and then cut to her in the bounce house with the label "My dog." What follows is a look at all the ways he watches her go about the life of an active toddler, always followed by her trusty companion. (Obviously, the pup pup is not truly babysitting as presumably the parent is the one filming.) In addition to being safe, she clearly adores the attention of her furry friend.

Do dogs understand when a pup barks on TV? We look into it
Dog barks outside in a lawn

We all love to see ourselves on the big screen, and our canines want to see themselves too. It's true that many dogs can watch television and enjoy it, particularly when they spot another furry friend up there. That's why you might show your beastie 101 Dalmations or throw on the Discovery channel if you're looking for a big reaction. This pup became particularly excited when he spotted a superhero dog on the TV in a dog video on TikTok entitled "Representation Matters."

The video starts with a clever four-legger watching Guardians of the Galaxy Volume 3 while sitting on his owner's bed. It's very clear that this movie is one of his favorites, and we're about to see why. Our dog friend is enraptured by the film but becomes even more excited when Cosmo, the pup in the film, comes onto the screen. The text tells us to "Watch my dog realize who the real hero is..." In his excitement, the little bud runs up to the screen barking and wagging his tail — thrilled to see Cosmo the dog save the day. You can see the pure joy in the pooch while he jumps up and down to celebrate.
