Hi guys! I'm getting a new dog (Pointing Griffon) which will go for ducks, woodcock and grouse. I do not want to use a E-collar for training, but I was wondering if I should get one for hunting. The only time I would use it is if the dog refuses the back command, let's say when chasing a crippled duck in too rough water. Some people told me it could save it's life. What do you think?
