White Line Separation - Cause? Treatment?

So the last time Amber got trimmed, which was about a week ago, my farrier told me that her white line is starting to separate. He recommended keeping the fissure very clean and use some Thrush Buster.

This has never been an issue before and I keep Amber's feet extremely clean. I'm not extremely knowledgeable on white line disease/white line separation (are they one in the same?), so I'd like some info.

It was too dark to take pictures this evening, but I will try for some tomorrow to add. She's not tender, and her feet otherwise look good (the farrier told me this).

Her pasture is dry except for one big, nasty puddle that will not go away near the water tub. The hose has a hole in it and whenever they're filling it, more water just gets put out. I'm thinking she's walking through this mud and packing her feet with the wet, nasty crap and that's behind this. She's a big water drinker and also likes to just play in the water for no reason, so I expect she spends some time there when she's turned out.

Another factor to be considered is the trim before this most recent one she was left a little long and as a result she was pretty long this time and she had much more flare than normal. Her fronts are worse than the hinds, but the beginnings of the separation is apparent on all four.

Like I said...she gets trimmed every 5-6 weeks, and I keep her feet very clean. She's never had this problem before either, and normally she's got great feet all around. But the puddle by the water tub and the long trim last time are the only two things I can think of. She got moved to the 'puddle pasture' in early December though, so that is a "new" situation there too - her old pasture didn't have any puddles.

I had my first experience with white line this past year with a student's horse. The farrier had her use Clean Trax soak, then desitin diaper cream for a week after. They trimmed her often and did a second round of Clean Trax after a couple trims.

Yes, pics would be good. Cause? Well you answered that by saying she had some flaring due to being left a bit too long between trims. Instead of 5 - 6 weeks, can you bring her down to 4 weeks? If this is not usually an issue, I expect she is getting the proper nutrition she needs already.

And yes, keep it clean and apply medication. Wash with a stiff brush using sunlight dish soap water, or lysol water; rinse, dry and apply medication of choice. I personally use athlete's foot cream/antibiotic cream/zinc oxide evenly mixed and apply every time I do my horse's feet.

Sorry, I think I might have been confusing in what I said - she isn't getting too long between trims, the trim before the last they didn't take enough off. This time they did. And yes, she is getting proper nutrition. She is also on a joint supplement that also is for hoof/coat. Turnout with grass and free choice hay.

Edit to add:

With that being said, if it becomes necessary I could bring her to 4 weeks of course.

Same difference -- too long between trims, or too long after a trim -- amounts to flares which amount to pulling on the white line which leads to WLD.

I believe being overweight can be a factor too? My gelding developed white line(I was told because he had shoes on and moisture got trapped underneath) I said pull the shoes he said no(I had wanted them pulled previous trims) so I said thanks for your services I won't be needing to make a new appointment. And I found someone else. Pulled shoes, dropped some weight to get any strain off his hoofwall. Set on a 4 week rotation and kept his white line very clean. A wire coat hanger can make for an excellent tool to get in the white line and scrape(better than a hoof pick) thrush buster and now he's white line disease free with no separation :)

She is overweight as well, but I have her on track to shed pounds. She's not obese but she is still too plump.

DressageIsToDance, I have been experiencing the recovery of WLD with my horse since last July/August. I bought him last July and WLD was diagnosed with the first trimming of my ownership. The separation went nearly 3/4 up to the coronary band and about 1.5 inches wide. Farrier and Vet worked together to remove the affected area and told me to apply Blu-cote and keep it dry. He was not sore/lame from the removal of the dead hoof. Farrier put on a bar shoe for additional support and we went on to jumping (very small jumps). Previous owner would go 8 weeks between shoeing and I heard that he was always long in the toe. I've done so much research on this topic. I suspect that in my case, the long toe put a strain on the hoof wall and that made it start to separate and allow the anaerobic fungus/bacteria to enter.

I advise to work with your farrier and vet to carve out all the separated area and treat with antiseptic (blue-cote or thrushbuster, etc.). This is important to expose the bacteria/fungus to air to kill it. I have also put my horse on "Replenishment Level" of Farrier's Formula Double Strength to grow his hoof out faster. I have seen a remarkable improvement and growth of his hooves and frog! We suspect that by his next shoeing in February, that the entire carved out area will be removed and he will be whole again :) I can post pictures if you'd like. Good Luck!

Separation is essentially due to laminitis &/or mechanical forces causing damage & separation. 'WLD' is the same as thrush - an opportunistic infection that finds a nice environment within the separated hoof. So to treat it all, it's important to treat the cause as well as treating infection, because once in there, if you ignore the infection, regardless what else you do, if conditions are right it can just eat away at the healthy tissue faster than the horse can grow it.

While 5-6 weekly is a good schedule for many horses, many benefit from & some do require more frequent. You talk about the trim before last being too long, saying 'more flar than normal'. This is a sign that it may be due to infrequent enough trimming, if she normally has flares - that means there is separation/stretching & the walls have let go their firm lamellar attachment with the pedal bone.

Without pics & more info, can only give very rough idea, but basically I would be trimming the walls right back & bevelling/rolling them strongly to relieve ground pressure from acting against the laminae. I would also keep on top of the infection, whether that included resecting, soaking, whatever.

Well, she really doesn't have any flair at all normally. I guess I didn't have the best choice of words there.

So separation is from laminitis, WLD is thrush essentially? So is this to say this is just WLD or is this caused by laminitis in my case?

My next appointment is set for 4 weeks though, this time. I'll talk to them about her possibly needing trims closer together.

I have pictures finally though. I picked them out and pressure washed with the hose.

ETA: And I do realize there is wear on the toes. Those are the hinds, and this has been addressed by a vet and the farrier, and she does this in the pasture, not under saddle.
