8 Gross (But Fixable) Reasons Your Labrador Smells So Bad

I know how much joy a Labrador Retriever brings into a home, but I also know that sometimes that joy comes with an unpleasant smell. You might notice a lingering odor even after a bath or a walk in the rain, and it can be frustrating to figure out why. Understanding what causes that smell helps you keep your Lab fresh, comfortable, and healthy.

In this article, I’ll walk through the most common reasons a Labrador develops a bad odor and what you can do about each one. From skin and ear issues to grooming habits and diet, you’ll see how small changes can make a big difference in your dog’s scent and overall well-being.

1) Skin infections causing foul odor

I’ve noticed that when my Labrador’s skin smells bad, it often points to an infection. Bacteria or yeast can grow quickly on the skin, especially if it stays damp or dirty. The result is a sour or musty odor that doesn’t go away after a bath. I check for signs like redness, scabs, or greasy patches. These can appear on the belly, paws, or ears. If my dog scratches or licks the same spot a lot, I take that as a warning sign. When I suspect an infection, I visit the vet. They can confirm whether it’s bacterial or fungal and prescribe medicated shampoo or antibiotics. Keeping my Lab’s coat clean and dry helps prevent the smell from returning.

2) Ear infections with fungal growth

I’ve noticed that when my Labrador’s ears start to smell musty or sour, it’s often a sign of a fungal ear infection. Labradors have floppy ears that trap moisture, creating the perfect environment for yeast or bacteria to grow. When I check my dog’s ears, I look for redness, discharge, or a greasy buildup. These signs usually mean it’s time to visit the vet. Ignoring them can make the infection worse and more painful for my dog. To help prevent this, I gently clean my Labrador’s ears after swimming or baths and keep them dry. Regular ear checks help me catch any problems early and keep that unpleasant smell from returning.

3) Wet dog smell from water-repellent coat

When my Labrador gets wet, that familiar “wet dog” smell often appears. It happens because water mixes with the natural oils that protect my dog’s coat. These oils are important for keeping the fur healthy and water-resistant, but they can release a musty odor when damp. The water-repellent coat traps moisture close to the skin, creating a warm environment for bacteria and yeast. As these microorganisms break down oils and skin debris, they produce compounds that smell unpleasant. Even after my Lab dries off, traces of these compounds can linger. Regular bathing with a gentle dog shampoo and thorough drying help reduce the smell without stripping away essential oils.

4) Poor grooming and infrequent baths

I’ve noticed that when I skip regular grooming, my Labrador’s coat starts to trap dirt and natural oils. This buildup can make the fur smell musty, especially after outdoor play or swimming. I try to brush my Lab at least once a week to remove loose hair and debris. During heavy shedding seasons, brushing more often helps reduce odor and keeps the coat cleaner. Bathing is also important, but I avoid overdoing it. I usually bathe my Lab every month or so, or sooner if the smell returns. Using a mild dog shampoo and rinsing thoroughly keeps the skin healthy and prevents lingering odors.

5) Gland issues emitting strong smell

I’ve learned that when my Labrador starts giving off a fishy or metallic odor, it often points to ahem, gland trouble. These small glands sit on either side of the butt and release a distinct scent when working normally. If they don’t empty properly, the fluid can build up and cause discomfort or infection. I usually notice signs like scooting, licking the area, or that unmistakable smell on furniture or bedding. My vet showed me how these glands might need manual expression if they stay full. Keeping my dog’s diet balanced and ensuring regular exercise helps reduce the problem. When the smell returns quickly or my dog seems irritated, I schedule a vet visit right away.

6) Allergies leading to skin irritation

I’ve learned that allergies can make my Labrador’s skin itchy, red, and inflamed, which often leads to a bad smell. When my dog scratches or licks too much, the skin can break, letting bacteria or yeast grow. That’s usually when the odor becomes noticeable. Common triggers include things like pollen, dust mites, or certain food ingredients such as beef, chicken, or wheat. My vet explained that these allergens can cause persistent itching, especially around the ears, paws, and belly. To help my Lab, I keep track of what food and environmental factors might cause flare-ups. Regular baths with a gentle, hypoallergenic shampoo and prompt veterinary care make a big difference. When I manage the allergies early, my dog smells fresher and feels much more comfortable.

7) Dental disease causing bad breath

I’ve learned that when my Labrador’s breath smells unusually foul, it often points to dental disease. Plaque and tartar can build up quickly, creating a home for bacteria that cause bad odors. If I ignore it, this buildup can lead to gingivitis or periodontal disease, which makes the smell worse and can even affect my dog’s overall health. I check my Lab’s teeth and gums regularly for redness, swelling, or yellow deposits. Brushing their teeth and scheduling professional cleanings help keep their mouth clean and their breath fresher.

8) Diet affecting body odor

I’ve noticed that what my Labrador eats can change how he smells. Certain ingredients, especially low-quality fillers or artificial additives, can upset his digestion and cause stronger body odors. When I switched to a balanced, high-quality diet with real meat and limited grains, his coat smelled cleaner and his breath improved. A healthy gut seems to help reduce unpleasant odors from the inside out. I also make sure he drinks plenty of water. Staying hydrated supports his skin and helps flush out waste products that might otherwise make him smell worse.

9) Rolling in smelly outdoor substances

I’ve noticed my Labrador loves to roll in things that smell awful to me but seem fascinating to him. This behavior often happens during walks or playtime outside, especially in grass, mud, or even animal droppings. From what I’ve learned, this instinct comes from their wild ancestors. Rolling in strong odors helped mask their scent while hunting or communicating with other dogs. When my Lab does this, I clean him right away with mild dog shampoo and plenty of water. I also try to keep him on a leash in areas where I know he might find something irresistible and smelly.

10) Excessive oil production on skin

I’ve noticed that Labradors often have naturally oily skin, which helps protect their coat and keep it water-resistant. Sometimes, though, the skin produces too much oil, and that’s when the smell starts to build up. When my Lab’s coat feels greasy or looks shiny, it usually means the sebaceous glands are overactive. This extra oil traps dirt and bacteria, creating a musty odor that regular baths can’t always fix. I learned that conditions like seborrhea, allergies, or hormonal imbalances can cause this overproduction. Keeping my Lab on a balanced diet and using a gentle, dog-safe shampoo helps control the oil and reduce the smell.
