I'm sure his is genetic but it didn't show up until after he was over 16 months old. But his mother has LP but developed them after a year old so since mom and son have LP I'm going to say genetic. Harvey and Brookie had tight knees at 6 to 12 months old. LP is very hard but when a puppy under the age of 1 has LP upon examination I wouldn't breed them of course. After a year it can be caused from injury and that is why LP is so hard again as some have posted. In my contract I will cover LP up to one year if it's a grade 4 by one year of age. Both my Harvey and Brookie have up to grade 3's but I have maintained weight and control of jumping and haven't had a problem with them in over year since maintaining weight control. I will not have surgery on either yorkie unless they show any signs of pain and intolerance to the LP. It's a very painful surgery and if I can avoid it I will unless ABSOLUTELY necessary

Donna, my adults have been checked but no official paper. i was thinking it would be nice to have it done every puppy that leaves here. That is why i was wondering what would be a good age. I wonder if a test on a 12-16 week old puppy is accurate.
