But it also looks like it was a while ago. Because you can see the rings in her hooves and the first rings only start to appear after a month.
Firstly, I differentiate between laminitis and founder, terms that many seem to use interchangeably & have different definitions of. IMO Laminitis is inflammation of the laminae, caused from metabolic(generally diet related) upsets. That is what causes the rings. Founder is the mechanical progression of the 'disease' if it's allowed to continue untreated, or not treated properly. Once the lamellar connection is weakened or broken down thru lami, the coffin bone can 'sink' &/or 'rotate' in relation to the hoof capsule and the hoof walls become separated from the dermal laminae which are connected to the coffin bone.
It does look like the top 3/4" of her poor front feet *may* be unaffected by lami, which could mean she hasn't suffered from this in the last month, give or take. However, as it's likely been ongoing - or frequent - before this and the hooves have become seriously foundered(the right front especially), just ensuring she is unlikely to suffer laminitis again is not going to make the issue go away. She will need careful hoof care & management until that healthy, well connected growth at the coronet can grow right down.
Just by the way she is walking and everything I think she is recovered from the founder. ....But to me the way she is walking and everything I don't think she will need them. Just by the growth of the hoof it doesn't look like it was that bad.
Sorry to be a 'fly in your ointment', but to me that sounds like your being extremely presumptive, based only on a few pics, and you don't understand the problems very well at all. Especially to advise against xrays, especially in light of that right front which I'd be happy to bet is quite 'rotated'! While by my def. you may be meaning lami when you say founder, and I agree that it *appears* she *may* not have suffered from this in the last few weeks or more, as I asked OP, how can you tell if she's lame in those shoes for a start?? Also while I am loath to say much from the vid - my computer's too slow to get much from it - it didn't look like she was walking quite right to me.
Once the horse is foundered there is no reason they can't go back to normal.
Another generalisation that may not hold up. I agree that *with the right treatment & management* the vast majority of horses are recoverable and a good likelihood that this is one of them, but there are some who do indeed have very good reasons why they cannot be returned 'to normal'.
Founder in the rear hooves is very rare and I don't see any signs of it there.
Founder *with rotation* is uncommon in rear hooves and generally speaking, the back feet, being used differently(not less) do tend to remain healthier, as they appear in this case. However, laminitis effects all hooves equally. It is the mechanical differences that tend to effect backs less. In this example, it does seem that the soles could well be 'sunk' and thin from founder, but they're nowhere near as bad as the fronts, and keeping them in good shape along with preventing further lami attacks may well be all they need to become healthy & strong.
She wouldn't be trotting around. My horse could barely move for like three days when he foundered.
You're confusing the severity of the symptoms with the disease. Some horses may have no or very mild symptoms when suffering lami or even founder. Some may be badly foundered at the same time as suffering a lami attack, etc. Also disregarding the palliative effects the shoes with pads are probably having.
But I would listen to professionals on that one.
Um, it seems that a 'professional' that did the 'corrective' shoeing was at least part of this mare's problem. I think becoming educated ourselves is vital, at very least because you can basically find 'professionals' that will tell you a range of different things, based on their experience, knowledge, etc. I've even turned up to new clients who's horses are seriously foundered & yet vets and 'master' farriers have said feet are fine! Regardless whether someone's a novice or an 'expert', they can still be good, bad or indifferent, so I wouldn't personally advise you blindly follow any 'professional' or otherwise, without doing your own homework first, to better analyse their opinions & approaches.
I would personally keep her on soft footing & no high impact exercise at least until she can be well trimmed, as she is already foundered and is shod, so all the load is effectively hung from disconnected walls(this does depend on the effect of the pads too). Once trimmed, the more exercise the better *so long as she is comfortable & her feet adequately protected*.
Another question I have is if it is good to get her walking around if she is willing? I took her for a walk (about 20 minutes) through the trails yesterday and she loved it- but I wan't to make sure it isn't going to be detrimental to her health..
The problem with allowing or forcing a horse to exercise on hard or rough ground(or even sometimes on soft if severe enough probs) when they have thin soles &/or weak heels(rotation aside) is that there is precious little 'armor' between P3 & internal structures and the outside world. The hoof is therefore open not only to pain but to abscessing from stone bruises, which can be huge and painful setbacks. Also if the horse has sensitive heels, no matter how 'well balanced' you may trim their feet, they will still continue to land toe-first, exacerbating founder, navicular and other issues. So regardless of whether the horse is obviously lame or apparently oblivious to their feet(and many people don't even recognise toe-first impacts either), if the feet appear thin soled &/or weak heeled, I would definitely be protecting them on hard ground and wouldn't advise barefoot on anything but yielding surfaces for now.
