Every dog owner knows the moment. You lean in for a cuddle and catch a whiff that makes you pull back slightly. A little bit of doggy smell is completely normal and honestly part of the package. But when the smell becomes strong, persistent, or unpleasant, it is usually trying to tell you something.

The good news is that most causes of dog odour are easy to identify and even easier to fix, once you know what you are dealing with.

Coat and skin oils: the most common culprit

Dogs naturally produce oils that keep their skin and coat healthy. Over time, especially between baths, these oils can build up and start to smell stronger, particularly on breeds with thick or double coats. This is completely normal, but it is also the easiest cause of odour to manage with a regular grooming routine.

A mousse shampoo for dogs is particularly good here because it lathers quickly and reaches deep into the coat without leaving heavy residue behind, which can sometimes happen with thicker liquid shampoos. Regular use, around every 4 to 6 weeks, keeps oil build-up in check without over-washing your dog and stripping the coat of the oils it actually needs.

Ears: a sneaky source of strong odour

Ear odour is one of the most common, and most overlooked, causes of dog smell. Floppy-eared breeds like Spaniels and Bassets are particularly prone to ear issues because reduced airflow creates a warm, moist environment where yeast and bacteria thrive.

A musty, yeasty smell from the ears is worth a gentle ear check. If you notice redness, discharge, or your dog scratching at their ears frequently, this is one area where a vet visit is more useful than a grooming product, since ear infections need proper diagnosis and treatment.

Skin folds and the breeds most affected

Dogs with skin folds, including French bulldogs, pugs, and English bulldogs, are especially prone to trapped moisture and bacteria building up between the folds. This can create a noticeably stronger odour, particularly in warm weather when sweat and humidity increase.

Daily wiping between the folds with a gentle pet-safe wipe, followed by thorough drying, is one of the most effective ways to manage this. It takes less than a minute but makes a real difference to comfort and smell.

Dental hygiene and bad breath

Sometimes the smell you are noticing is not coming from the coat at all. Plaque build-up on teeth creates bacteria that causes persistent bad breath, which can be mistaken for general body odour. Regular use of dental finger wipes, alongside professional cleans when needed, helps keep this under control without requiring a full toothbrush routine, which many dogs find stressful.

A simple weekly routine to keep odour in check

Most dog odour comes down to a handful of manageable causes, and almost all of them respond well to a consistent, gentle grooming routine. Pay attention to where the smell is coming from, and you are usually halfway to solving it.
