Does Your Dog’s Coat Smell Bad? Should You Be Concerned?

Dogs aren’t supposed to smell like roses, but if your pet’s coat has a persistent bad odour, it’s not just about being dirty. A healthy dog should have a mild, natural scent that fades after a good bath. If the smell lingers or returns quickly, there’s usually an underlying reason that needs attention.

2. Is It Normal for a Dog to Smell?

Some odours are expected—like that classic “wet dog” smell after rain. But strong, musty, or fishy odours aren’t normal. If you’re bathing your dog regularly and they still smell bad, their coat might be telling you something about their health.

3. What Could Be Causing the Smell?

a) Skin Infections
Bacterial and fungal infections, often triggered by allergies or humidity, can cause a sour or yeasty smell. If your dog is scratching more than usual, has red patches, or has greasy fur, a vet check is needed.

b) Poor Diet & Gut Health
A dog’s skin health is closely linked to their diet. Low-quality food, food intolerances, or digestive issues can lead to dull fur and an unpleasant odour. Omega-3-rich foods and a balanced diet can help.

c) Ear or Dental Issues
If the smell seems to come from their head rather than their coat, check their ears and mouth. Ear infections and dental diseases are common culprits. A foul-smelling breath or head shaking can be warning signs.

d) Impacted Anal Glands
A strong, fishy smell that lingers even after a bath? It could be your dog’s anal glands needing attention. These glands naturally release a scent, but when they become blocked, they can cause discomfort and a strong odour.

e) Overbathing or Wrong Shampoo
Ironically, bathing your dog too often—or using harsh shampoos—can strip their skin of natural oils, leading to an imbalance that causes even more odour. Stick to a bathing schedule that suits your dog’s breed and coat type.

4. What Can You Do to Keep Your Dog Smelling Fresh?

• Check for underlying health issues first—if the smell is persistent, don’t just cover it up with shampoos.

• Improve their diet with high-quality food and supplements for coat health.

• Groom regularly to remove dirt, debris, and excess oils before they build up.

• Clean ears and teeth to prevent hidden sources of odour.

• Ensure proper drying after baths—damp fur can trap bacteria and worsen the smell.

5. When Should You See a Vet?

If your dog’s smell is accompanied by excessive scratching, hair loss, red skin, or discomfort, it’s not just a hygiene issue—it’s a medical one. A vet visit can help identify infections, allergies, or other underlying causes.

Your dog’s coat is more than just fur—it’s a reflection of their health. If the bad smell isn’t going away, it’s time to look beyond the shampoo bottle.
