Ik kwam tevens een serie interessante röntgenopnames tegen van puppy's. Daaruit is het zeer duidelijk op te maken dat je rustig aan moet doen met puppy's. Ik wilde het toch even delen omdat ik bij enkele mensen hier in de buurt toch mijn hart vasthoudt vanwege de activiteiten die ze al ondernemen.
Twee weken oude pup

This is an X-ray of a puppy at 2 weeks old - just look to see how far the bones have to grow to just become proper bony joints, let alone become strong articulating joints that have correct feedback into the brain... this is why it is imperative that we don't over-exercise our puppies, and certainly not jump them or train them too hard before they are fully developed. This is different age categories for different breeds, and if the dog has had any specific problems during it's puppyhood. Please be careful at this stage so the dog's joints will last well as they age! Longevity is key!

I have just stumbled across this X-ray of a 2 week old puppy with the caption “look to see how far the bones have to grow to just become proper bony joints, let alone become strong articulating joints that have correct feedback into the brain” I am a radiologist and this is complete misinformation.
The apparent gap between the long bones of the femur and the tibia is due to epiphyseal cartilage, which is not visible on an X-ray. Central ossification of the epiphyseal cartilage will occur over months and this will be visible on an X-ray. The long bones that you see in the X-ray will never “grow to ever meet each other” as you are seeing the metaphyseal portion.
To illustrate (the red arrows are pre-existing as I took this image off the internet), I have posted a very young child’s knee. Below the red arrows is the normal growth plate. Below that is a ball-like bony structure that represents the normal immature femoral epiphysis.
This knee is more advanced in age than the 2 week old puppy. On the X-ray on the left, you can now see the partially ossified epiphyses of the femur and the tibia. However, there is still a gap between the bones. You can see on the MRI image on the right, the gap is visible as unossified epiphyseal cartilage. In other words, there is a “proper” joint in a 2 week old puppy. Therefore, there are normal periarticular proprioreceptors or “correct feedback” to the brain.
To use this X-ray to espouse the dangers of over-exercise or overtraining is at best careless. Many of the joint problems people are describing may also be related to underlying dysplasia or other pre-existing abnormalities. There seem to be people on this post who are now afraid to even walk their dogs. Please use common sense. Overtraining is an issue with dogs of all ages, not just puppies.
