We already know that a dog's eyesight is not its most developed sense, but did you know that it can see thanks to its sense of smell? Dog owners looking for a product to neutralize the smell of animal urine often ask us this question about the canine sense of smell...
Why does my dog always urinate in the same place?
In a short video, cognitive scientist Alexandra Horowitz explains how a dog's overdeveloped sense of smell enables it to smell a scent, even if only a faint trace remains. She also explains how dogs can see things invisible to the human eye. Here are the facts that caught our attention!
Some interesting facts about the dog's sense of smell
Dogs have over 300 million odor-capturing cells, while humans have only 5 million.
The dog's nostrils breathe independently of each other, which helps it determine where the scent is coming from.
The olfactory system takes up much more space in the dog's brain than in the human brain. Dogs can therefore remember a much wider variety of smells than humans.
If a human can recognize the smell of a spoonful of sugar in a cup of coffee, then a dog could recognize the same smell in a million gallons of water - the equivalent of two Olympic-sized swimming pools!
Dogs can smell things we can't even see. Thanks to its vomeronasal organ, the dog is able to detect the hormones that all animals and humans naturally release. This is what helps the dog recognize potential companions and distinguish between friendly animals and predators.
It's also the same organ that alerts the dog to our emotional state, and can even make him recognize a pregnant woman or a sick person.
So that's why your dog can still smell urine, even if it's been gone for weeks or months. Watch the video to learn more about a dog's sense of smell!
By the way, if you really want your dog to stop returning to that same spot, you'll need to use an odor neutralizer, like Urine Odor Neutralizer!
Is Your Dog Really Dirty… or Just Oily?
Does your dog’s coat feel greasy just a couple of days after a bath? Does it attract dirt easily, look dull, or have a lingering odor despite regular grooming?
If so, your dog may not simply be dirty—it may have an oily coat. With the right products and a few simple habits, you can help restore your dog’s coat to its natural, healthy balance.
Dirty Coat vs. Oily Coat: What’s the Difference?
A dirty coat and an oily coat often look similar, but they aren’t the same thing.
Dirt comes from your dog’s environment—mud, dust, pollen, sand, or other debris picked up during daily adventures.
Oil, on the other hand, is produced naturally by your dog’s skin. These natural oils, known as sebum, play an important role in keeping the skin hydrated and the coat healthy. However, when too much oil builds up, it can leave the coat feeling sticky, attract more dirt, and trap unpleasant odors.
The result? Your dog may look and smell dirty even after a bath.
What Makes a Dog’s Coat Greasy?
Like humans, dogs naturally produce oils that help protect their skin and coat. When these oils become excessive, however, they can trap dirt and odors. The American Kennel Club emphasizes the importance of maintaining a healthy grooming routine appropriate for your dog’s coat type.
There isn’t a single cause of excess oil production. Several factors can contribute to an oily coat, including:
Breed characteristics—some breeds naturally produce more oil than others
Humid weather
Frequent swimming
Product buildup from previous grooming products
Infrequent bathing
Seasonal shedding
Certain skin conditions
If your dog’s coat suddenly becomes unusually oily or is accompanied by redness, itching, hair loss, or skin irritation, consult your veterinarian.
5 Signs Your Dog May Have an Oily Coat
Not sure whether excess oil is the problem? Here are a few common signs:
The coat feels greasy or sticky to the touch.
Dirt and debris cling to the coat easily.
Unpleasant odors return quickly after bathing.
The coat appears dull or heavy.
Fur begins to separate into oily clumps instead of feeling soft and fluffy.
If several of these signs sound familiar, your dog may benefit from a different bathing routine rather than simply more frequent baths.
Why Regular Shampoo Isn’t Always Enough
Most pet shampoos are formulated for routine coat cleaning and maintenance. They remove everyday dirt while helping keep the skin and coat healthy.
However, when excess oil has built up, a regular shampoo may struggle to remove it completely. The remaining oil can continue trapping dirt and odors, making the coat feel dirty again sooner than expected.
In these situations, a degreasing shampoo can be an excellent first step.

The Ideal Bath Routine for a Healthy Coat
Step 1: Brush the Coat
Brush the coat thoroughly to remove loose hair and surface debris.
Step 2: Remove Excess Oil
If the coat feels greasy, start with Purodora Lab Degreasing Shampoo to remove excess oil and deep-set dirt.
Step 3: Use a Coat-Specific Shampoo
Follow with a Purodora Lab shampoo tailored to your pet’s coat type or specific grooming needs.
Step 4: Maintain the Coat Between Baths
Maintain the coat between baths with regular brushing. Use a Purodora Lab leave-in spray as needed to eliminate odors and keep the coat fresh.
How Often Should You Use a Degreasing Shampoo?
A degreasing shampoo isn’t intended for every bath.
Instead, use it whenever your dog’s coat has accumulated excess oil, feels greasy, or is heavily soiled. Once the buildup has been removed, continue with a shampoo appropriate for your dog’s coat type as part of your regular grooming routine.
The right balance keeps your pet’s coat clean, fresh, and comfortable without over-cleansing.
Frequently Asked Questions
Why does my dog’s coat feel greasy after a bath?
If excess oil isn’t completely removed during bathing, it can continue attracting dirt and trapping odors. Using a degreasing shampoo before your regular shampoo may help restore the coat’s natural balance.
Can excess oil make my dog smell bad?
Yes. Excess oil can trap environmental odors and bacteria, causing unpleasant smells to linger even after bathing.
Should I use a degreasing shampoo every time I bathe my dog?
Not necessarily. Degreasing shampoos are best used when excess oil or heavy buildup is present. For routine bathing, choose a Purodora Lab pet shampoo suited to your dog’s coat type.
Why should I use two shampoos?
Think of it as a two-step approach. A degreasing shampoo removes excess oil and buildup when needed, while your regular shampoo addresses your pet’s specific coat needs and helps maintain long-term coat health.
Healthy Coats Start with the Right Routine
Every dog’s coat is different. While regular grooming is essential, understanding what your pet’s coat needs can make all the difference.
If your dog’s coat feels oily, attracts dirt quickly, or doesn’t stay fresh after bathing, excess oil—not dirt—may be the real issue. Starting with Purodora Lab’s Degreasing Shampoo and following with the right coat-specific shampoo can help restore a healthier, cleaner, and more comfortable coat.
With the right routine, you’ll spend less time fighting grease and odors—and more time enjoying a happy, healthy pet.
