Doggy odour usually comes from sebum and bacteria on the skin and coat — and gets stronger when the coat is wet. A strong unpleasant smell is usually linked to one of these causes: ear inflammation, plaque and tartar, full anal glands, skin folds, dermatitis, or a dirty bed or collar. Regular washing with a suitable shampoo and thorough drying, brushing, cleaning ears and teeth, and washing the bed all help. If the smell is strong and appeared suddenly, see a vet.
7 causes of odour
| Source | How to tell | What to do |
|---|---|---|
| Skin and coat | The whole dog smells, more after rain | Washing, drying, brushing |
| Ears | A sour or sweetish smell from the ears, head shaking | Clean with an ear cleaner; if inflamed, see a vet |
| Mouth | Bad breath, yellow plaque on the teeth | Tooth brushing, dental chews, cleaning at the vet |
| Anal glands | A sharp fishy smell, scooting on the floor | Expression by a vet or groomer |
| Skin folds | Smell and redness in face or tail folds | Clean and dry the folds daily |
| Dermatitis, yeast | Greasy coat, itching, dandruff, redness | Diagnosis and a medicated shampoo as prescribed |
| Bed, collar, clothes | The smell stays even after bathing the dog | Regular washing |
How often to bathe a dog
Most dogs need a bath every 3–6 weeks or when dirty. Bathing too often with harsh products dries out the skin, and the sebaceous glands work harder — so the smell gets worse. Use a dog shampoo that suits the coat type and skin, and rinse it out thoroughly. Don't use human shampoo — it has a different pH. How to choose a product and bathe correctly is in dog shampoo: how to choose, and the range is in shampoos and conditioners.
Drying is half the battle
A damp coat and undercoat are ideal for bacteria. After a bath or a walk in the rain, towel your dog and finish with a hair dryer on a warm setting, especially dogs with a thick undercoat. Don't let your dog sleep on a damp bed.
Between baths
- Brush your dog 1–3 times a week: dirt and grease go along with dead hair.
- Use coat-refreshing sprays such as Nature's Miracle: they neutralise odours without a bath. There's also dog perfume in the perfumes and deodorants section. But remember: a spray doesn't remove the cause.
- Wipe paws and belly after walks with pet wipes.
Ears and teeth
Clean the ears every 1–2 weeks with a special cleaner such as Beaphar Ear Cleaner. If the inside of the ear is red, has dark discharge or smells bad, see a vet — it may be otitis. More in how to clean your dog's ears.
Bad breath is a common cause of dog smell in the home. Brush your dog's teeth with dog toothpaste several times a week and give dental treats, such as Croci Dental-Veg with green tea and mint. How to get your dog used to tooth brushing is in how to brush a dog's teeth. Tartar is removed at the vet.
Diet and weight
Food quality affects odour too: with an unsuitable diet or a food allergy, the skin becomes greasy, itching and dandruff appear, and gas becomes frequent. A balanced food with omega-3 and omega-6 fatty acids improves skin and coat. Overweight dogs have deeper skin folds and find it harder to groom themselves, so losing weight helps.
A home without dog smell
- Wash the bed, blankets and removable covers every 1–2 weeks.
- Wash the collar, harness and toys — they soak up sebum.
- Vacuum and air the rooms regularly.
- Use pet odour neutralisers on stains and spots where your dog likes to lie.
