Guys, OP is brand new to horse owning, & it sounds like the whole horse experience. This is understandably a devastating experience. Cut them some slack & put yourself in their shoes before replying!
OP, unfortunately re your money etc, you'll just have to chalk that up to experience I'm afraid, but I personally wouldn't blame you for wanting to 'start fresh'. If you do want to just be done with it though, I would personally only consider it ethical to be 'free to a good home' only to a rehab organisation or someone knowledgeable & willing to put in what it takes to rehab/manage her properly.
Depending on a number of factors & being a newbie to horses, it's also possible you may not do her any favours by keeping her, as you may have some hard yards ahead & we don't know your situation as to whether it will give her the best chances. With more information, we may be able to tell you whether it's likely to be on the easier or harder side to manage/fix her.
Poppy & others that have said laminitis is easily managed - yes, it *can well be*, but not always, particularly if 'chronic', depending on what exactly that means. Also Poppy, laminitis IS 'founder', by another name. But some do use the term differently, for eg. Laminitis being just the inflammation that causes the initial damage & founder being mechanical changes to the hoof/capsule such as 'rotation' &/or 'sinking' of P3 within the capsule - hence the term 'founder'. In the case of Okan of Cypress, his vet seems to like the term 'hoof inflammation' & be reluctant to call anything short of ?? Laminitis!
Metabolic/diet related issues that cause the inflammation are *usually* easily managed *assuming people are in a situation they can manage*. Mechanical changes also may or may not be easy(ish), difficult or impossible to 'fix'. While in some 'circles' these type of changes are still looked upon as 'incureable', that is far from the case *generally*. Look up hoofrehab.com & barehoofcare.com for some examples & more info.
Now OP, I'll await more info from you on the other thread. Check out the link in my signature below(not my site BTW) for tips on critique pix. Info on condition, diet, management and such would be helpful. In the meantime, I'd get xrays done ASAP & look into finding some professional help that is *experienced in successful rehab* of the condition, as unfortunately all equine vets & farriers aren't equal in that regard. Depending on where you are, contacting the above mentioned sites may be able to refer you to good help in your neck of the woods.
