Suze, I am saying that a breeder can rapidly improve the hips of their dogs by using hip x-rays and removing the defective dogs from their breeding program. I use prelims because I want to know when a dog is 1 year old instead of when it is 2 years old. This makes a difference in my decisions and plans for the future of that dog. In other words, I don't want to plan my breeding program around a dog that will be neutered/spayed. It is easier for me to place a dog that I have had a year, than to place one that I have had for two years.
I don't advocate testing young puppies as this is not practical. I do prelims at one year of age. All the best, Susan Cochran ----- Original Message ----- From: "Susan A.
