Overview
If your dog smells like old socks, the source is often damp fur, dirty paws, waxy ears or a skin issue rather than anything unusual. It can also happen after exercise, rainy walks or if your dog has rolled in something unpleasant. If the smell is strong, keeps coming back, or comes with redness, itching or discharge, it’s worth looking a bit closer.
Things To Check
1. Notice whether the smell is strongest after walks, muddy turnout, swimming or grooming.
2. Check the paws, especially between the toes, for trapped dirt, moisture, redness or soreness.
3. Look inside the ears for wax, discharge, a strong smell or signs your dog is scratching them more than usual.
4. Part the coat and look for dandruff, oily patches, redness, scabs or areas your dog keeps licking.
5. Check whether the skin smells worse in one area, which can sometimes point to a local issue rather than general dog smell.
6. Think about whether your dog has recently had a bath, as a coat that stays damp can start to smell quickly.
7. Look at bedding, collars and harnesses, because smells can build up there and transfer back onto the coat.
Common Causes
The most common cause is simply moisture and everyday dirt sitting in the coat, especially if your dog has a thick or oily coat type. Wet paws, muddy fur and bedding that stays a bit damp can all create that stale smell.
Waxy or irritated ears are another common reason, and ear odour can sometimes seem to spread across the whole dog. Skin irritation, excess oil, yeast overgrowth or a minor skin infection can also cause a musty or sock-like smell.
Less commonly, the smell can come from a dental problem, anal gland discomfort or something your dog has rolled in. If the odour is persistent or unusual for your dog, it’s sensible to keep an eye on it rather than just masking it.
What To Do
Start with a proper check of the paws, ears, coat and bedding. If your dog is muddy or wet, dry them thoroughly, especially between the toes and in the feathering or undercoat if they have one.
Wash bedding regularly and make sure collars, harnesses and coats are cleaned too, since they can hold onto smells. If your dog’s coat tends to trap dirt, a steady grooming routine can help remove debris before it starts to smell.
Keep a note of when the smell starts, where it seems strongest and whether it comes with itching, licking, shaking the head or skin changes. That makes it easier to spot a pattern.
If the smell keeps returning, doesn’t improve with routine grooming, or seems linked to a sore area, it’s sensible to get it checked by a vet.
When To Contact A Vet
Contact your vet if the smell is strong and persistent, or if your dog also has itching, redness, soreness, discharge from the ears, scabs, hair loss, head shaking or licking at one area. These signs can suggest a skin, ear or other problem that needs proper assessment.
Products That May Help
If your dog’s smell seems to be coming from their coat, paws or ears, a gentle grooming routine can help you keep on top of day-to-day hygiene between washes and checks.
