Fat and the working nose: how dietary fats support scent work
A detection dog's nose is its job. Handlers think about training, rest and temperature. Fewer think about fat.
What the research suggests
A frequently cited study from Auburn University's canine performance program found that the fat in a dog's diet affected olfactory performance after exercise. Diets rich in polyunsaturated fatty acids (PUFAs), commonly found in fish oils, have been linked to better detection sensitivity, likely by supporting the membranes in the nose.
Why fish oil
Every Inukshuk formula includes herring oil. Marine formulas add salmon oil and use 100% ocean-sourced animal proteins.
Energy matters too
A tired dog is a less accurate dog. Highly digestible formulas mean more energy for work, and as Inukshuk puts it, better digestion lets the nose do more of its valuable work and not miss a point.
Practical tips for handlers
- Feed consistently. Big diet swings can affect performance.
- Don't feed a big meal right before a search.
- Keep dogs hydrated. Panting dries the nose.

Questions owners ask
Does diet affect a dog's sense of smell?
Research on working dogs suggests it can. Diets with more polyunsaturated fats, like those in fish oil, have been associated with better olfactory performance.
