What to do when faced with patous in the mountains

What is a patou?

The patou is a mountain dog (often of the Montagne des Pyrénées breed) used to guard flocks. From an early age, it grows up among the sheep, which it considers its own family.

It acts instinctively to deter any presence it perceives as a threat: foxes, wolves… or hikers who are too curious.

Remember: the patou is not aggressive, but it takes its work very seriously.

The right thing to do

Don’t try to pet him: he’s not a pet, he’s a working dog.
Spot the flock: if you see the ewes, keep your distance and go around them if possible.
Stay calm: if the dog approaches or barks, don’t shout or run. This could alarm him even more.
Walk slowly: continue on your way without making any sudden movements, and without staring into the dog’s eyes.
Keep your dog on a short lead: the patou could perceive it as a predator.

A precious cohabitation

Patous play a key role in protecting herds from the return of the wolf to the Alps. They enable farmers to preserve pastoralism, while ensuring the safety of the animals without resorting to violence.
By following a few simple rules, everyone can find their place in the mountains: hikers, herds, farmers… and guard dogs.
