I'm a member of FB Finnish Basenji group. I have seen grouse hunting pictures on the site previously. Just searched the member posts, and one member, Arto, said he had submitted hunting articles to Suomen Basenji (Finland), Jakt och Jägare (Sweden) and The Modern Basenji (USA) Also, a survey last year showed four members answered that they let their dog(s) run unrestrained while hunting.
Even though the first two articles are in Finnish and Swedish, if you can find them, you may get some useful tips by using a translation website. Or if it does not work, contact me.
