I enjoyed reading the link above about breeding for different traits. Especially, the one posted by Ludi, "Heritability of Herding Related Traits". This was very helpful to me. It has been my experience that eye is becoming harder to find around here. I have noticed this as a general trend around here. I have often wondered how eye is passed on. Is it dominant or recessive? Based on the study in the link mentioned, it seems to be recessive. In my conversations with fellow handlers here in Texas, most are reluctant to breed a sticky or very strong eyed dog. My experience with recessive genes tells me that if you want a moderate amount of eye, you should probably select a puppy from two parents with medium to heavy eye. Possibly even more eye than you are comfortable with. It seems that the dogs that are considered not useful for having too much eye may also lack power. I have a good friend who has a very strong eyed dog that also happens to be his best farm dog. However, his eye does keep him from being a top trial dog. I had a female from him that was really nice. Arthur Allen once said "The only time you can have too much eye is when there is not enough power to back it up." In summary, I think this knowledge will help me select my next puppy or the next bitch to breed my dog to. However, it is a scientific fact that not all of the puppies will inherit the same amount of eye, power, etc. We can only hope to improve the odds. On the bright side, it is very uncommon that I receive a dog in for training or raise a puppy that does not work. Eye and Power are only two of the many traits that make a dog good. There are many other traits to consider in a breeding program. It is no surprise that outstanding young dogs seem to be few and far between.
