Hello Dr. Deb,
What is your 'take' on a horse born with a wry nose. Is it genetic or the result of bad positioning in the womb or something else?
I ask because I am caring for one now and get asked this question often.
We have contacted Dr. Jim Schumacher at Univ of TN, sent photos etc and he says our foal's case is correctable with reconstructive surgery, and not as severe as some he has worked on.

Hi Dr. Deb,
Here is a photo of the wry nose , the front teeth are actually off set and do not match up at all and the left nostril is squished almost closed.A very strange abnormality.

Thank you very much, Allen! I hope the foal has some hope of quality of life, or else they euthanatize before it gets miserable for him. This birth defect is of genetic origin and especially common in miniature ponies and Arabs.

BTW, I just gave you and Navegador some national mention -- did a feature for Equus Magazine on 'Mastery -- What it is and how to find it' and used the photo you posted here of you working him on the 'palo verde' at the Spanish Walk. Look for it to come out, I hope, sometime this fall, kind of interpolated between parts of the horse breed history series. Cheers -- Dr. Deb

Hello Dr. Deb,
The foal ( we nicknamed her Barbara, after that famous singer with a funny nose) is doing very well, thriving on 3.5 gallons of foal formula a day in addition to what milk she can cajole out of her reluctant dam, and a selection of solid creep feeds ( milk pellets and cold pressed alfalfa w/ essential oils) .. The dam seems to only allow her to nurse if handler is nearby ( much better than a month ago when she had to be caught and held) .. Dr. Schumacher said he will do the reconstructive surgery after six months of age.. Until then he says the facial bones do not hold screws well enough to keep a steel plate attached. A piece of rib is harvested and grafted into place, a complicated surgery yes, but it is the only chance an afflicted foal has to live a normal life. We are very lucky to have surgeons that innovate such procedures. I have seen 'before and after' pics and the results ( even years later) are quite acceptable. Dr Schumacher told be he did not think the condition was inheritable until recently when a same pair of stallion and mare produced two consecutative foals both with wry nose.
This mare has an extremely!! short back which made me think that room in the uterus might have been limited and thus a factor. Just an old wives tale?
Thanks for the heads up on the article I will look for it. "Mastery" is an elusive concept, though sometimes an especially talented and willing horse can make one look good (the gray Arab on the dais was the first horse I trained) .

I'd never heard of this before! How alarming. I wonder how often a cleft palate accompanies this.

Many years ago I saw a pony who had an offset nose. They said the dam had been kicked while pregnant and that it had broken the foal's nose. I've always wondered about that. And now, after learning about this, I'm thinking it was probably genetic. Wouldn't a foal deep inside the womb be pretty well protected from a kick?

That's gotta wreak havoc with the teeth.

Good luck with her Allen.

Aloha,
I am sure that story was just made up by somebody that did not know better.
Here is a photo of my sidekick Shane holding Barbara's mouth open to show the mismatched front teeth. This is why a radical reconstructive surgery must be attempted.
There are more pics on a FB page showing how the daily care of this is progressing .. she is thriving exceptionally well, at a rather exorbidant cost in milk replacement firmula. So my daily goal is to get her eating more solid food , Today she 'discovered' alfalfa and ate half a bucket in just a couple hours. even though she has to go at the food sideways.

Aloha -- this is an excellent example of the penalty we force horses to pay when we breed for just one or a few traits that seem important to us. Miniatures are highly prone to this genetic disease or malformation of the skull, and the reason is that breeders have considered getting the small size and the "cuteness" so important that they were willing to breed stallions and mares that had been parents to foals with wry nose, and the breeders knew this.

In cattle breeding, bulls that throw genetic diseases have their papers pulled. The saying among cattle breeders is, "the bull is half the herd." This is just as true with horses, but since mares are not normally served in herds as cows are, it is not as obvious to horse breeders. I also think that horse breeders have been extremely short-sighted and unwise, going as I said above for very small and trivial, superficial characteristics rather than putting as first priority the health and wellbeing of the individual, and the long-term sustainability of the breed.

This is why I said in the Equus Magazine feature on American Pharoah, "this is no longer a horse race, it's a clone war." Inbreeding kills. -- Dr. Deb

So, is the only way to fix that with radical outcrossing? Or does the sire or dam with the heaviest inbreeding score still tend to dominate the outcomes

That isn't how genetic dominance works, Bruce.

One should never breed any horse known to produce any genetic disease. -- Dr. Deb

Wry nose - update
Hello Dr. Deb, et.al.
Here is a photo of ' Barbara' the Arabian filly born last January with a wry nose. On July 6th she underwent corrective surgery at the Univ. of TN by Dr. Jim Schumacher. He told me that he has done about 15 of these radical procedures over the years, and that while only doing one or two a year makes it hard to completely perfect the operation, the results in Barbara's case are quite acceptable if not remarkable. With regular dental work to establish then maintain proper occlusion of her teeth she will be able to live a complete normal life..

Here is a link to a TV news story about Barbara after the operation
