I had a Toy Poodle with it back in the 70's. I now know that the line was known for it. I was grooming her one night when one of her back legs slipped as I lifted her front end up, and I thought that she would never stop screaming.
This was back in the days that dogs were put in an RJ splint after surgery. It was the full groove job, and taking some bone to reposition the tendon. I was told to totally restrict movement for 12 weeks. I always 100% follow vet orders, yet know lots of people that got fed up of it, and had huge problems with their dogs. However, that's another matter. She eventually had the second back leg done, so again was crated for lengthy periods.
Many years later when she had an x-ray for something or other, the pin could clearly be seen, still in place. I lost her just before her 17th birthday, but she could do a standing jump to my shoulder well into her teens. I never for a moment, regretted having the operation. She was almost a year old when she had her first leg done.
However, last year I had a bitch that had the operation on one leg only. She is 5 years old. Different breed, but a huge difference when I found out that they are no longer splinted. And not even loads of padding and bandages! Different vet, but told exactly the same. Sucess rate depended on restraining my bitch for 12 weeks. He did admit after the operation that he was glad that he hadn't had one this bad when he first qualified, so I guess he had his work cut out. He prefers to use 2 clips but there just wasn't room. And the repositioning of the tendon was extremely difficult. (I guessed because it was so badly out of line.)
I had to work at getting weight off her after all the rest time, but it was worth it, and I can see such a huge difference now when she runs chasing my Border Collie. :-)
