Overview
A bad smell in dogs can be a sign of infection, especially if it’s coming from the ears, skin, paws or around the mouth. But smell alone doesn’t mean infection, and it can also be caused by dirt, moisture, grease, anal gland issues or a coat that simply needs a proper wash.
The key is to check where the smell is coming from and whether there are other changes such as redness, discharge, soreness or scratching. That gives you a much better idea of whether it’s likely to be a hygiene issue or something that needs vet advice.
Things To Check
1. Try to work out exactly where the smell is strongest. A smell from the ears, paws, skin folds, mouth or rear end can point to different causes.
2. Look for redness, swelling, crusting, discharge, broken skin or a sticky feel on the coat.
3. Notice whether your dog is scratching, licking, rubbing, shaking their head or chewing at a particular area more than usual.
4. Check if the smell gets worse after rain, swimming, muddy walks or exercise.
5. Have a look inside the ears and between the toes if your dog allows it. A strong odour with wax, moisture or soreness can be worth paying attention to.
6. Think about whether the coat has become greasy, damp, matted or difficult to dry properly after washing.
7. Check the rear end area for staining, soiling or signs your dog may have had trouble keeping clean.
Common Causes
The most common reason is simply a dirty, wet or greasy coat, especially in dogs with thicker fur, skin folds or a history of getting muddy. These smells often improve with better drying and routine grooming.
Skin irritation or an ear problem is also common. Yeast, bacteria and trapped moisture can all create a noticeable smell, often with itchiness, redness or discharge as well.
Paw odour can happen when feet stay damp, muddy or irritated for long periods, particularly after walks or wet weather.
Less commonly, smell can come from a dental problem, anal gland issue or a skin infection that needs veterinary treatment.
What To Do
Start by washing or wiping the area only if it’s safe to do so and your dog is happy to let you. Dry them well afterwards, especially in folds, between the toes and under the ears.
Keep an eye on whether the smell improves over a day or two with normal grooming and drying. If it keeps coming back, or it’s linked with sore skin, ear discharge, persistent licking or head shaking, it’s sensible to speak to your vet.
Try to keep muddy areas, damp bedding and heavily soiled coats under control, as these often make smells worse.
