also how old is he?

He is coming four... I have NO IDEA about his parents LOL. I did have his briother, he was a red roan and had the same color hooves.

Here is a pic, it is TERRIBLE lol, cropped from the only photo I could find that showed one of them. It is night out so I can't take a pic right now...

And no, that hair on his leg is NOT white, but golden.

Conformation?

I'll have to take a pic...

My chestnut has a small amount of white on one leg......and all 4 hooves are striped too.


I am not sure if this counts as a white sclera....but he does have more white around his eye than any of my other horses.


The pic below shows the extent of the one leg's white.

Yes he's a snowcap by phenotype. If he's night blind then by current research he's homozygous and I do see his "white" or "amber hooves" on the black legs.

If you haven't looked lately she said he is night blind.

Yea, but I'm still not holding to the theory that amber hooves is an indication of homozygous. Because I've got a mare here who meets several qualifications of being considered homozygous. Like 6 out of 6 foals from a QH stallion all colored, and she's night blind, (indicated to be seen only in the homozygous horses) and she does NOT have amber hooves. Her hooves are stripped. So if amber hooves is an indicator of homozygous then why does the mare who's already on the road to proving her homozygous genetics not have amber hooves?

Perhaps it's like the paw prints on a Tobiano - the presence is a pretty darn good indicator of homozygosity, but doesn't guarantee it and doesn't mean that if they aren't present the horse is hetero for Tobi.

In no way does the research published in "Equine Opthalomolgy" say that only LP/LP can be 'night blind' - it says SCNB (Stationary Congenital Night Blindness) appears to be homozygous to LP/LP. There are other forms/causes of 'Night Blindness' that do appear in all breeds. I've never read anything that said that amber hooves were a requirement for LP/LP but that it was thought that amber hooves might indicate that that particular horse was LP/LP. Of course there is no way - yet - to prove LP/LP today - it's still all an 'educated/uneducated guess'.

I just stumbled across this thread and thought I would mention a mare I used to have. She was a solid black (no markings) Pure Polish Arabian mare. Her hooves were solid white no stripes nothing. I have pictures of this mare from ten years prior to me getting her and she had black hooves. I wonder if it was a diet malfunction.

Pete our old horse also have striped hooves always has he's solid chesnut with darker points and his hooves are all striped.

I always though both of those were interesting.

It also does not mean because they are present they are Homozygous as there are several with pawprints that have a non Tobiano parent.
