Bear in mind too that we don't all get shot at all the time while walking our dogs. I live in Brittany so I can't speak for any other region....if there's a big hunt on, they usually our signs out and have watchers.
Be sensible. Keep your dog on a lead. Hunting can go on on both public land and private where permission has been given. Some areas are more sensitive than others. In Brittany, you can walk all over the Gr34 with no worries. (The coastal path). Inland, you'll find that most land is private and you can't access it. It can feel frustrating....acres of beautiful forests and its all private so keep out! The best thing is to contact thentourist office where you want to visit and they can tell you of the best walks in the region.
There are some wonderful walks around us that are totally safe. Just don't assume to be able to walk where you want.
I've heard that in the south beware truffle zones.....they'll shoot you!
