OK, got time for a quick reply & more questions for you... sorry that I've only skimmed other's replies too, so may repeat stuff...
Some of you may remember my threads about my mare, Ricci and her foot/leg problems. Basically, her feet hurt, causing strain on her tendons in the back of her front legs and [we assume] in the soft tissue of her feet. I have had my vet out. Approximately 9 months ago, he took x-rays to rule out navicular,
Vaguely remember. Got the link to the thread? Got some more pics of now? Eg. Idfferent solar angles showing depth & heel height/balance?
Re 'rule out navicular', I presume that means damage/degradation to nav. Bone has not occurred? Were any scans done to show if there was any damage to DDFT?
Basically, heel pain/'navicular syndrome' is very common, due mainly to the cushy environments and little exercise our horses get. Horses may just never have developed the strong digital cushions & lateral cartilages needed to support proper hoof function of a mature animal. When there is heel pain, the horse tries to avoid the discomfort by 'tippy toeing' and not using the back of his foot. Unfortunately that exacerbates the issues, as less use = less health and the heels can then also become contracted, thrushy, overlong, more sensitive.... This is aside from different fashions of trimming/shoeing, etc. Toe first landings mean the 'shock absorbers'(digital cushions) of the horse's feet aren't working and there is little capacity with the forces hitting the tip of P3 for shock absorbtion directly through the bones & joints. In addition, both the DDFT & the are under strain on impact in this position and it is thought that this strain as the DDFT rubs against the back of the nav. Bone causes it to become damaged and subsequently damages the nav. Bone itself.
So.... regardless of the way a horse may be trimmed, toe first landings can still happen. You might trim a 'perfect' angle onto a hoof, but if there's heel sensitivity, he'll still avoid the pain, despite how 'ideal' it is. So the primary emphasis is getting the horse to *comfortably* land heel first, which will in turn start developing the structures for good hoof function & shock absorbtion. To this end, I would treat for thrush(whether it's obvious or not), avoid paring any frog, except for any manky flappy bits - certainly don't allow routine frog paring, as seems to have been done, and watch how she's walking and pad/boot her feet wherever necessary to allow comfortable & proper movement. I would also consider that while her heels are still weak, although the 'ideal' heel length may be shorter than it is ATM(The sole pic to me appears there's little to come off anyway, but pics aren't most accurate info), for her comfort it *may* be beneficial to leave that little extra length for the time being.
Regarding the trim, as others have said, pics when she's due don't show the best, and while IMO there are indeed some probs with what's been done, but superficially at least, I don't think it's too bad, or apart from the frog paring, not likely to contribute to her pain or cause further probs. I gather by 'bubbles' you mean the horizontal bulges in growth? I think while imbalance can indeed exacerbate this, it is metabolic stress(generally diet) that leads to the laminitis that causes the initial weakness. So again on that front too, I don't think the trim is the primary concern.
First, he put natural balance shoes on her. They seemed to help at first and then the second time around, I saw it wasn't helping.
Yeah, read a good article about NB(& other 'corrective' shoes/trims) recently that I'll see if I can dredge up for you. Basically NB shoes are not meant to be a long term answer anyway. While it seems that your horse does have a bit of a long toe, it appears from the one sole pic there *may not* be much stretching at the toe laminae(altho obviously fair bit at quarters) seems like there is not that much depth to the sole & it's still a bit thin, so the length is possibly mostly due to the pedal bone having 'sunk' in the capsule, in which case there is little that should come off the length now, or 'backed up' at the front, until the internal structures are able to become higher in the capsule.
She said the bubbly wave she has going on is indication that she is growing an angle that is not consistent with the trim she has been getting. She said her quarters were left too wide, and she has actually grown too much heel. Everything she said made sense, and Ricci obviously needs a change. If my current farrier was working, I would see evidence of some kind of improvement, right?
Agree with her on the quarters, but see above re 'bubbly line' & heel length. Without more info can only say she may be right.... or she may be wrong, but there's more to it than that. Re evidence of improvement, as trimming is but one of many factors of hoof health, not necessarily, sorry.
Anyway, hope that's been of some help & food for thought. Gotta go now but I'll keep an eye out for more info, etc.
