You have a sample size of 1, and it was admittedly an oversize dog which is a huge factor in HD. Genetics is another huge factor. Was the dog evaluated at 2 for hip scores? You say you ran him too hard. What did that entail?
This is your original post: Now, I am concerned about the hard stops as well. My rules are them not fat, and no jumping like in and out of truck beds until 12-15 months old, no jumping for anything, and only about 5 minutes exercise per month of Life so far. No long walks or jogs or bicycle riding running, nothing like that as a puppy.
Your second post:The 5 minutes of EXERCISE per month of Life, means a 4 month old gets 20 minutes of hard exercise like running after the ball in soft sand, HARD WORKOUT twice a day. That is not counting, walking him, off leash play, loose in the yard, more than that but the HARD EXERCISE is 20 minutes TWICE A DAY.
There is some conflicting information between the two recommendations. First says no long walks. Second says walks don't count etc.
I agree that that forced exercise, including fetch with a high drive dog, should be limited. I understand and appreciate that a beloved dog suffered with arthritis and you are trying to help others avoid that terrible condition.
There is evidence that under exercising a puppy can cause problems as well. Cartilage doesn't thicken. A dogs body, just like ours, becomes resilient through exercise. I suggest that owners speak with their breeder and do their own research. Don't take my word for it. I'm just a dumb grunt.
I'll post a link to this article again. It is written by a DVM. Thanks

Over the years, many breeders, trainers, and owners have said that puppies should not be exercised until the growth plates are closed. I have been asked to radiograph 12-month-old dogs to make sure their growth plates are closed. Recently, a well-regarded colleague told me that he had an owner...

From the article.
"So, jarring, high impact activity may be risk factors for some joint conditions. But keep in mind that none of these studies fully considered the genetic component of the dogs. Further, there is very good evidence that being overweight as a puppy in more likely to contribute to joint disease. "
"Exercise places demands on joint cartilage, which becomes conditioned to transmit the stresses to which it is subjected. Mild to moderate levels of running in dogs may stimulate adaptation. Most studies of moderate running indicate no injury to articular cartilage, assuming there are no abnormal biomechanical stresses acting on the joints, such as hip or elbow dysplasia or rupture of the cranial cruciate ligament (exercise certainly accelerates the development of arthritis in abnormal joints)."
"Young beagle dogs jogging 4 km/d (2.5 miles), at a speed of 4 km/h (2.5 mph) at a 15-degree incline on a treadmill for 15 weeks had no damage to cartilage and a 6% increase in cartilage stiffness and an 11% increase in cartilage thickness, all positive changes. Jogging 20 km/d (12 miles) on a treadmill for 15 weeks did not result in further changes. Skeletally immature dogs subjected to 15 weeks of jogging at a rate of 40 km/d (
24 miles per day!!!) had no change in cartilage content. However, running 20 km/d for
nearly 1 yearresulted in a 6% reduction in cartilage thickness of the medial femoral condyle, with an 11% reduction in proteoglycan content (the part of the cartilage that gives it stiffness and wear resistance). In similar studies of running 40 km/d, the effects of training for 1 year on young canine articular cartilage found that there was no visible cartilage damage, but there was some softening of the cartilage. But these are all
huge distances. Think about running a marathon or half marathon 5 days a week for a year! Like Forrest Gump, just keep on running for no particular reason."
