I don't have any critique photos, but I'm going out tomorrow and will try to get some. Her toes are very stretched, I trimmed and rolled the hoof and even beveled the toe from beneath to relieve some of the leverage. There was definite old bruising/tearing in the laminae. I have trimmed her twice now ( once just before the x-rays and once again 2 weeks ago ) and will be touch-up trimming her every 4 weeks to address the issues.
The abscess has already popped, so we're out of that "frying pan". There is a huge dip as you've mentioned, though I don't think "founder" ever came up ( I know that doesn't mean it didn't happen, just possibly unnoticed as she wasn't "off" ).
As for the possible side-bone, as a matter of aging, this horse is only about 8 years old. What are the possible effects on her long term soundness/health?
