Yes, he actually didn't make it. The broken jaw healed completley before I bought him - out of place enough that he could not chew at all - which is why at 8 months old this Mustang HORSE only weighted 47 pounds.
However, he was also deaf as a doornail, which was slightly annonying. The worse was that the skull injury left him with a memory of only about 6 hours. This meant that in the morning he would have to be halter broken to take him out of his stall and out to his turn out. He was usually ok to lead back to his stall, but in the morning it was spend another hour or two to teach him how to lead.
After three years of this, we did the math. He was costing about $6 a day to feed his speical diet - thank goodness his stall was donated by the stable. But there came a time when we could not justify the expense of keeping him, yet there was no way we could rehome him. He was humanely euthanized with a bullet and donated to a big cat rescue.
