The last time she was overdue for a trim was in July/August-ish. She hadn't been trimmed all summer, and her feet were horrible. Could they be from that long ago? Since
Firstly I agree with those who say it doesn't look too bad, that they're hopefully surface cracks which haven't gone through the wall. I would expect that ensuring good management will just allow them to grow out.
Considering how her feet were when shod, I'd say the founder is also a part of it. The laminae had become stretched and there was a lot of stress, especially at the front of the feet. While her feet have been well looked after since, there would have still been weakness in the walls & as mentioned, probably infection underlying too. I would ensure that the hooves are kept well 'rolled' and the walls are relieved, never allowed to overgrow, for a while longer, until some strong connections have grown down to the base. It may be that the hooves are not long, but for what *these* hooves need *at this time* they may need a brush up more regularly to ensure the toes stay relieved. Perhaps you could ask your trimmer how to keep on top of the mustang roll between trims?
caused by chronic laminitis. This may not be the case but that's what I've heard about rings sometimes. This is best diagnosed by a good set of radiographs and with a veteriniarian experienced with laminitis situations.
Pechos, you're right that the rings can signify laminitis. If you take a look at Wallaby's other thread, you'll see where these feet came from. Differentiating between lami(inflammation & damage to laminae) and founder(mechanical progression of weak laminae & incorrect hoofcare), laminitis can't be diagnosed with x-rays. It's the degree of founder(coffin bone 'dropped' or 'rotated' in the capsule) that can be seen by x-rays. But it doesn't take an xray to tell that these feet were also foundered when shod. The rings signify that there has been ongoing regular laminitis for some time, but hopefully Wallaby has her diet etc sorted, along with good hoofcare, so that can become a thing of the past.
it just means she had a laminitic like episode or something like that, and hopefully not that she actually has had laminitis. The rings aren't as bad in the newer hoof
See above Wallaby. I'm sure she has had lami, pretty constantly over the last year or so. The way the horse was trimmed when shod exacerbated it & she was foundered too. However, if she's no longer laminitic, great! She can *start* to grow well connected hooves. But they will be weak & need TLC until the new tight growth reaches the bottom.
Regarding your BO, I hope her 'craziness' doesn't extend to feeding her grain, sweet feed or putting her out to gorge lush grass. If so, you've got to change this ASAP & feed her only a healthy, low carb diet. Founder isn't just to do with obesity, but is linked with it because many obese horses develop insuline resistance, which causes laminitis, in the same way people develop diabetes. Even if they were never fat, they can develop IR & it doesn't go away, must always be managed, even if fat horses slim down. Even without IR, horses aren't designed to digest rich, starchy food and 'hind gut acidosis' is another common cause of lami.
A quick question to those with the experience. When a hoof forms a toe crack from excess pressure, does it start from ground level and work its way up the hoof wall?
Quick answer - generally yes. If there is a lot of lamellar damage at some point, the weak wall can crack there tho, and if there was an abscess at the coroner band & stress there, they can occasionally start at the top. Regarding wild horses or those with enough movement on hard/rough ground 'self trimming', this happens constantly and the hooves don't get to the point of overgrowth. Once they get to that point, depending on hoof conformation, wall strength, etc, they will either break off in chunks, &/or will flare & split.
