Yarpen and his hip dysplasia

While this blog has been mostly about Falka, this post will be all about Yarpen. Though it won’t be as fun as the other posts… As I write it, Yarpen is curled up, spaced out on Tramadol, with an incision in his belly and bald patches on his hips. But let’s start from the beginning….

Yarpen was bought as a pet foremost, but also I had hopes he would become a stud dog. When he was 3 years old, I had his hips and elbows Xrayed to see where we stood. I expected good results, as other than not being particularly jumpy, he didn’t have any problems that I could see. Well, a HD D score was a very brutal wakeup call… Unfortunately, I don’t have copies of his original Xrays, but I do know that his right hip was worse than left. We followed the specialists advice and modified the exercise a little, but other than that, made sure that he had enough of it to build up muscle mass to hold up the joints. Of course, breeding was out of question.

Fast forward 3 years, I started noticing first signs of the dreaded disease. It started very gently, with a shorter gait on the back right leg. Then it moved on to reluctance to pee while standing on right leg. So, we started physiotherapy. It was absolutely amazing and I could see progress pretty much straight away. However, due to progressing osteo-arthritis (OA) we had to limit Yarpen’s exercise further. And this becomes a very slippery slope…  The more pain the dog experiences, the less they want to move. But, with a severely deformed joint, it is the muscles that need to hold the joint up. With no exercise, the muscles start to shrink, other body parts are taking more load than they should and the consequences spread from the affected joint to the whole muscular-skeletal system.

Yarpen is now over 8 years old. According to our physiotherapist, I managed to keep him in optimum condition, with him still being able to jump on a grooming table or in the bath. But, he is extremely fragile to contusions… Over the last 3 months he has had several strains on both hips, requiring heavy medication and rest. Of course, the rest = no exercise, which leads to further muscle loss… His last strain was probably the worst, as I couldn’t even pinpoint what cause it. He didn’t slip, Falka didn’t jump on him, he didn’t get hit by anything… and yet one day he woke up with trouble to get up and refused to put weight on the right leg. At this point I realised that we need to do SOMETHING, or this will be the beginning of the end.

Our options were:

  1. Continue with medication, strict rest to heal up and then physiotherapy.
  2. Surgical procedure
  3. Stem cell therapy

Option 1 was what we did up until now, and it seemed to stop working. The outcomes of option 2 are not really well guaranteed, and considering the recovery time is about 6 months per one hip, it would mean that for the rest of his life he would be in pain. Plus, as he weighs just a little less than me, this would not be practically possible, as my husband works a lot, and I wouldn’t be physically capable to carry him in and out for toilet. So, we have decided to go for the stem cell therapy. The one major drawback to it is that this is the only treatment not covered by our insurance, which means Christmas (and whole next year by the looks of it!) will be tight, but hey, it’s just money….

We have had the first stage of the process done yesterday. Yarpen was measured and examined in any way possible. Of course, he had an Xray done. Not only on his hips, but also his back, as he started showing symptoms of back problems too.

His hips look like this:


You will notice the horrible socket of the right hip, with severe OA. Note also the shape of the femoral head, it should be like a ball. Yarpen’s resemble more a pyramid than a ball… The neck of the bone is also malformed, instead of clear narrowing under the head, the bone just started building up. If you look close enough, you will also see a difference in the thickness of muscle on both sides.

His back Xray showed that he started to have changes in his spine. Because of abnormal movement, his disk started to calcify, with some changes on the walls of vertebrae. This will need addressing too.


A thermal-image camera showed clear signs of inflammation in his pelvis, radiating through his lumbar region (white – hot, going through yellow, orange, red to green and blue being cold). There is also some muscle inflammation in the thoracic region, as shown in the thermal signal and in physical examination, but this appears to be only muscular. The lack of heat signal on his glutes shows a muscle mass loss.


A weight-spread analysis showed that he is now walking evenly, with one back leg carrying only 12% of the body mass. This is of course compensated by the front legs, which carry more than they should.

The hip joint fluid, instead of being clear and viscous, is watery, filled with blood and leukocytes, showing clear signs of inflammation. In both joints….

The diagnostics left us in no doubt – Yarpen is in pain.

What we are going to do about this now. First, he had a blood sample collected, from which a platelet rich plasma was extracted. This was then injected into his hip joints, which will hopefully stimulate the “clean-up” process of the inflammation. We hope to see no blood in the fluid next time we sample it. We also collected a sample of his adipose tissue (fatty cells) from his belly. This required a general anaesthetic and a small incision. These cells will be sent out to a lab and grown for a couple of weeks. After Christmas, these cells will be injected in his hips and spinal column to regenerate the deteriorating cartilage. All this will be followed by a series of laser treatments and physiotherapy. We are hoping to do this soon after Christmas. And it should give us in excess of 18 months of vastly improved life… We’ll see what will happen when we get there!

Writing what I think about breeding against HD would take a whole book, so I will state it only very concisely. Hip dysplasia IS genetic. Whether it causes problems or not is affected by environment to a certain degree. But there MUST be an underlying genetic predisposition for this to happen. Selecting against HD is not easy, but it is absolutely doable. I am a quantitative geneticist, working on traits exactly like HD in my day job, and it just boggles my mind how many breeders prefer to hide behind the “you can get a good pup after dysplastic parents, and a dysplastic pup after good parents”. Yes, the same goes for conformation champions, and somehow this doesn’t negate the drive you have for breeding for the next rosette! Some dogs may be more affected than others, some will have horrendous Xrays and seemingly no issues, other will go limp with slight strain. But, there is nothing worse than seeing your dog wanting to walk, wanting to work with you, and not being able too. So I implore you, please, test your breeding dogs, and for puppy buyers, PLEASE make sure you don’t make the same mistake as me, don’t buy pup after untested parents! The fact that the pups parents appear to be fine at the age of 3-5 does NOT mean that they are free of dysplasia.

Yarpen’s score is HD D. This table shows the translation of the score to the systems in other countrieshd-scores

The median score for the Russian Black Terriers in the UK up to 2014 was 25. According to this, an average RBT in the UK has hips similar to Yarpen. I feel absolutely sick to my stomach to think that so many of our dogs will suffer from this horrible disease…

  1. My springer is 10.5 years old. He has bilateral hip displacia. Aug 2015 he had first lot of stem cells. 6 months after we had X Ray’s and more injections the improvement is amazing. He has lead only walks. Hydrotherapy every week. No medication. In Jan 17 he will have 3rd injections to keep topping up plus another X Ray to see how the hips are. He was lame. Had been leaning on one side and had 3″ muscle loss front and rear left legs. After 10 swims he was even. Not lame. My insurance pays up to £8,000 per condition. Direct Line Advanced Policy. Far cheaper than 2 new hips and quick and easy for dog to get over.


    1. Oh wow, I never expected this blog entry would go this far! Thank you so much, I was wondering if his age would impact the growth… Waiting impatiently till we can actually use them! 🙂
