Many dog owners report that after switching their pets to a raw food diet, their dogs have fresher breath, a cleaner-smelling coat, and less pungent stools. But is there any science behind these claims? While research on raw feeding is still developing, some studies and veterinary insights suggest that diet plays a significant role in a dog’s overall odour.

Fresher Breath

One of the most commonly cited benefits of raw feeding is improved oral health. Since chewing on raw meaty bones helps mechanically remove plaque and tartar, it can contribute to fresher breath. Unlike kibble, which can leave starchy residues that encourage bacterial growth, raw food does not contain processed carbohydrates that may contribute to bad breath.

Cleaner-Smelling Coat

A dog’s coat odour is closely linked to their diet. Some proponents of raw feeding report that dogs on such diets develop shinier coats and healthier skin, which reduces the build-up of oils that can cause strong odours. Essential fatty acids found in raw food support skin health and may help prevent odour-related issues.

• Balanced omega-3 and omega-6 fatty acids in raw diets contribute to skin and coat health, reducing excessive oil production that leads to unpleasant smells. (Source)

Less Pungent Stools

One of the most noticeable benefits of raw feeding is firmer, less smelly stools. This is due to:

• Higher digestibility: Dogs absorb more nutrients from raw food, leaving less waste to be excreted.

• Lower carbohydrate content: Processed dog food often contains fillers that contribute to larger, smellier stools.

• Healthier gut microbiome: A study on raw-fed dogs found that they exhibited different gut bacteria profiles, which may contribute to less odorous waste. (Source)

Conclusion

While many owners report a reduction in dog odour after switching to raw food, scientific studies on the subject are still emerging. However, research suggests that a raw diet may promote better oral health, healthier skin, and improved digestion, all of which contribute to less odour from breath, coat, and stools.
