Doves have dry feathers. A lot of field champions don't like to pick up doves.
Force fetch if done properly as a conditioned retreive will make your dog rock solid and more reliable regardless of breed or breeding.
I like the Mike Lardy method which starts with the conditioned "hold". The conditioning progresses into force fetch from there.
I personally don't care for the toe pinch, we have to trim nails from time to time and don't want them freaking out over their feet being touched. We use the ear pinch and have had sucess with it. Ear rubs and good ear cleaning practices prevent the dogs from being bothered by touching the ears.
