Breeding dogs needs to be a responsible voluntary decision, not an accident or something that you do because it would be cute to have puppies. Every one of those pups could be the responsiblity of their owner for up to 20 years in the future, and they do not remain a puppy for long. Breeding a livestock guardian means you should be providing people with a robust, healthy dog capable of guarding against large predators for an average of 12 years, sometimes longer.
So if you have had an xray and hip score performed on you dog or bitch and the result is not good, should you breed from that animal? The answer is no, but it is also not a completely simple answer.
If you haven't read the section on genetics of dysplasia, read that section now to assist you in working out why breeders need to make informed breeding choices.
OFA recommend to breeders that they choose their breeding partners by:
- only breed normal hip scored animals together - in other words, don't take a dog with a normal score and breed a poor scored animal to it thereby introducing dysplastic genes
- only breed normal hip scored animals to others that have normal scoring ancestry
- select sires that show they produce a low incidence of hip dysplasia
- check your bloodline scores against the breed average and always breed with dogs that are higher than the average.
I would add that another thing breeders can do to help prevent hip dysplasia in their bloodlines is to give high quality information to their puppy buyers on how to raise thier puppy correctly - the importance of nutrition on the growing pup, what constitutes too much food and what constitutes correct and enough exercise.
