Appaloosa mane falling out

My mare started shedding her summer coat this past week and I noticed that she appears to be shedding her mane as well. I usually just comb it through with my fingers but the last couple of times I have combed it with an actual brush and both times the brush was full of hair at the end. Her mane is all ready super thin...

Is it normal for an appaloosa, or any breed for that matter, to shed their mane when they are shedding their winter or summer coats? I have never noticed it before in any other horse that I have owned. She is UTD on everything and in good health.

Is the maybe scratching it and its just kinda clinging and falling out on your brush?

That's how it was with my paint stud. Little snot kept rubbing on the oak trees.

I'm interested in what everyone has to say also...my Paint gelding has this problem. When he started shedding his winter coat this year his mane was also shedding out in handfuls! My brush would be full and it would also come out if I ran my hand down and thru it. I have never had a horse do this before that I can recall and I had read that it can be caused by excessive selenium? He was on a supplement that had quite a bit in it so I quit that and it does seem to be improved but could be due to shedding season pretty much ending?

I would guess more likely that it is a combination of your horse being itchy and rubbing his neck on things that caused some mane hair to break off and you brushing more because of shedding causing some more hair to break off or fall out.

The only breed I have ever heard of shedding mane and tail are curilies

My appaloosa never even had a mane to fall out,

All of my horses have shed out some of their mane in the spring. Some of them will shed out more then others.

The more you brush it, the more it will fall out also!! Trick it to not touch it! Appaloosas are known for not good hair, but brushing will only worsen what little she has.

I've heard, appy's are prone to having very thin manes and normally no tails at all! I've been to shows with completely bald appy's with only docks and short stubby manes - be thankful you have one on her!

I have never heard of a horse shedding their mane...that's.....just not normal. I would question her nutrition. If her hooves are cracking up a storm like they are and loosing mane...I'd start looking at what you are putting into her, or lack there of.
