“Hello good afternoon. Here are a few lines of how we met you:
It was Halloween afternoon when I took Marcelino to the vet because his right eye suddenly looked very bad. Two months after struggling to save his eyeball and two operations later, it is decided to remove it with much disappointment for so much effort in vain; however, having only one eye was not the worst thing that 2014 was going to leave us: Marce had begun to limp. At first we blamed it on some blow or fall but when it seemed that it improved it began to limp more. A CT scan was the only solution. The result was two herniated discs and an adrenal cyst that prevented the sending of information from his brain to his left patuca. The options were various surgeries with very few guarantees or try it through physiotherapy. The joint decision was not to intervene and we quickly started with the physio sessions. At home we also worked daily but we needed something that could support him so he wouldn’t drag so much. The disability was already noticeable but we missed the walks outside our garden.
Physiotherapy and medication had lost almost all mobility but with your chair we could take walks, run and play. Marcellin learned to take curves, to go backwards, to climb some step… He felt like a dog again. Or rather ‘perropersona’ as we always defined him. Finally with the loss of control of sphincters derived from the lack of nerve impulses, came the urine infections practically chained and on July 2 of this year he began his journey to the rainbow. It was a long and painful process, especially hard in its end but I will always have seen him run around until the last day with his Orthocanis chair. This is broadly their story. I don’t mean you to publish it. Use the data you want. I hadn’t talked about all this again and that’s why it’s been so long. Thank you from Marce and myself.”
I write these lines after a long conversation with Dr. Alberto Palleroni, an expert in psychology and animal neurology at Harvard University. To give you an idea. On the day of Felix Rodríguez de la Fuente’s tragic accident on his trip to Alaska, Alberto was traveling with him in another helicopter. The dog and human being have been sharing paths for a long time. These have not always been in favor of the company, but rather of the need of both. The wolf shared the carrion that the human left of the large prey and the human shared the hunt for the small pieces hunted by the wolf. Little by little our species have adapted in a surprising way. Together we chased prey for 160 kilometers to hunt them down. Biomechanically we were practically the only ones who could be prepared. We evolve with them and thanks to them. We conquered the Arctic and the Middle East thanks to your help. Even Muhammad introduced into the Qur’an a note about the importance of the 
The Saluki is the most evolved dog. Our survival depended on its purity. They can run at 80 kilometers per hour for about 16 kilometers which no dam was able to withstand no matter how fast it was. Over the past 200 years, our endeavor to create artificial breeds tailored solely to our contemporary needs has not been a fair deal for such an old friend. Most of the pathologies in the hip of current dog breeds is due to artificial variation of the knee angle. What is known by a companion of Alberto Palleroni, Dr. Donald B. Slocum, world-renowned leader in orthopedics and one of the fathers of sports medicine as a subspecialty of Orthopedics. One of its legacies are the well-known Slocum plates used in veterinary orthopedic surgery globally. The angle of the knee has come to vary, in relation to the ancient Saluki race, up to 30 degrees. Biomechanically that variation is what is wreaking havoc on the hips of today’s races. Hopefully we will find together, a way to redirect the deep wound we have made in the DNA of our
