Hi everyone, I'm not a GSD person, but from my internet searches I think this board is a good place for my question.

My Vizsla puppy came up lame on his rear hind leg about 5 months ago (he's 16 months now). He had xrays done by a regular vet and then he was seen by an orthopedic surgeon. Both seemed stumped as to what was wrong with him. His xrays are picture perfect, he has great hips, no inflammation in any joints. Both diagnosed him with panosteitis.

I'm just not so sure. He has symptoms that just don't match up. Here's his symptoms:

--It started when he was playing rough with another dog and came to us holding up the leg. We thought CCL tear. The vet found nothing on the xray though and no drawer movement.

--At the beginning he held up his rear right leg. Over time he started using it again and now almost never picks it up. But he still has a hitch in his gait when he trots. He's a show dog, and will gait for me in the ring, but when gaiting himself in a field he'' gait perfectly for several feet and then all of a sudden it's like he skips on his back legs.

--He's also a national level field dog (well, puppy). He runs hard and fine when allowed to, he has no issues with running at all, only trotting. He's probably running through the issue.

--A few months ago, exercise seemed to make it worse. Now it doesn't. In fact, he seems a little better when he gets the chance to stretch his legs.

--He has no pain when I touch his bones or squeeze them or manipulate them. He won't let the vet touch him anymore. (he's had enough of being stretched and pulled)

--He's not better or worse in the morning or night or after waking up.

--The lameness has never switched legs. All 5 months it's been the same leg, and the hitch in his gait is the main and only symptom other than occasionally holding up a leg.

--He's been tested for lyme-negative.

--His back leg muscles are extremely well muscled for a Vizsla, probably the most muscled I've seen in the breed. No muscle atrophy at all.

--The only time he got majorly worse is after his booster shots. They gave him the shots in the leg he limps on, and for 2 weeks after he was holding the leg up a lot again.

--NSAIDs don't seem to help.

--Pano did not show up on the xrays. The vets and orthopedic specialist just couldn't see anything else that it could be.


I just find it so hard to believe he's going to get better on his own. I've been searching the internet for months, reading medical documents, trying to find something that fits, and nothing does perfectly.

Sorry for the long post....so can anyone explain to me the exact symptoms their dog had when they had pano? Did the vet actually see it on the xray? Did anyone NOT see shifting leg lameness or it getting better or worse and NSAIDs making no difference?

Thanks so much for your help, I'm desperate!

Here is a blurry video, you can see the skip I'm talking about and also see how he canters a lot to resist trotting. Does this look like pano?

My GSD had three bouts of Pano. At 6 mos, it lasted for three weeks, rear leg, 8 mos, front leg and 10 mos rear and front, two last ones lasted two weeks. I had her spayed at 6 mos(she was limping for two days at this time, and I asked vet tech to look for splinter or injury to her foot) she was on Rimadyl for the spay pain, for 6 days, but still limped. I then went to Ascription for the bouts after that, which maybe took the edge off of her pain.
I fed Nutro Natural Lg. breed pup til 6 mos. and then switched to RAW diet. My pup was long legged and large for a female, 27" and 88# at one yr. She is still this size at 21 mos, maybe a bit lighter as I am trying to keep her lean.
Not sure how size and diet played into it. I would maybe look at the spine if pano didn't show on x-rays. My GSD was never diagnosed thru the x-ray, just thru the symptoms. Because your pups limp has lasted more than a few weeks, I would definitely look beyond the leg. The shot theory is interesting, maybe they got a nerve or ligament...good luck, others will hopefully give more info, advice!

hopefully it's pano. my Shep had it for 4 months. towards the end of the 4th month you could see him getting better and then it was gone. during the pano days he was on a very light walk regiment. there was no ball playing or going to the dog park. i started massaging my dog's legs. he seemed to like it. i still massage his legs. i say no long walks, no running or jumping for awhile. good luck.

You do not seem to be giving your pup any down time to heal. Strained tendoms or sprains would not show up on x ray.

Try joining Boxerworld.com there are some exceptionally knowledgable moderators on that board.

I have gotten fantastic Nutritional and health information there.

Best of luck.

My ten mnth old GSD was diagnosed with Pano also. Like your pup it was only in one leg (front) and showed nothing in x-rays. Like you I did not believe this diagnosis.

Many vets and lots of $ our issue was fixed by an equine vet. Apparently there was damage to the growth plate. He sedated the dog, took fluid off the joint and injected pups blood antigens. This was done twice, over two months. $400.00 a session.

We have had a crazy healthy, happy limp free pup for three months.

My vet insisted that my girl had pano but we came to find out that it is a condition called "gracilis muscle contraction". We went to an orthopedic surgeon who diagnosed her.

You mentioned that his hind end is very well muscled, that is one of the symptoms of this disease. The muscle on the hind end close to the groin area is called the gracilis and the condition makes it seem really muscular but it is actually where the muscle is turning into fibirious tissue.

You also mention a hitch in his gait. This is another one of the symptoms of this disease. My girl started off limping which progressed to a hitch in her gait and that progressed to her hind leg turning inwards.

There is very little know about this disease therefore it is often passed off as some other condition.

Hope this is not what your baby has but it is something to consider as you have had no other answers.
