No stone bruise. So it didn't originate in the foot. Diddly's tendon is now very swollen and there's a pulse, and he has a crack at the top of his foot where the hoof meets the coronary band. Either our other horse trod on his foot, or he got a thorn or something in it.
We are trying to get hold of the vet, but we can't seem to. :(
There are more things that can happen to hooves than stone bruises. Sounds like an abscess that burst on the coronary. This can happen if they bash their coronary band, but it commonly happens because of general ill health in the hoof, for whatever reason - often imbalance, laminitis, bad 'seedy toe', etc. Best treatment for this is well trimmed hooves that aren't peripherally loaded, and lots of free movement. In conjunction with poulticing &/or mild antiseptic treatment to prevent further infection of the compromised wall.
I would just like to know why some people say don't get it opened just so I can be educated to other views.
Very good. At any rate, if your horse already has a 'split' it's been & gone now. *Generally* I wouldn't advise 'digging out' an abscess. It leaves the hoof open to further infection, antiseptic on live tissue can further damage & inhibit healing, and especially if in the sole, removes the 'armour plating' of the hoof capsule to protect the live foot inside. It is also common for vets to 'dig' in the wrong place, to 'follow tracts' that aren't there, etc. All in all, IME it's generally better to leave the area intact, barring a good trim, poultice the foot and encourage(but not force) movement, which will bring it more quickly to a head. I also wouldn't use bute as a rule, as suppressing the inflammation can just suppress the abscess without it resolving, making it take longer & possibly cause other issues. There are other non-anti-inflammatory pain relievers that can be used if necessary.
I bought her, as a 3 year old. I had her about 3 weeks, when she pulled a muscle and was off for nearly a year. She was at a vital stage in her training, as she was just broken. She's never quite caught up with other ponies her age, due to that, and she developed the smallest of string halts.
Good that she got a year off. Much better not to ride a 3yo baby. Must have been a major 'muscle pull' to be off for a year though - sounds like she was indeed broken! I know about Australian Stringhalt, but it's very different to what others call it. I'm interested in how did the stringhalt relate to her issues? I thought it was a neurological problem.
