Thought we had found a nice natured family horse. Bit young, but sensible type. Had it vetted and failed. 1-2 after flex test and uneven behind lunged on hard service. Apparently shod badly behind. Vet suggests letting sellers have it shod properly and re-vetting in a couple of weeks, or walking away. Also commented thought it seemed a bit green for what we are looking for (not much clue about lunging??).
Head says walk away, heart says there?s something about it that?s worth a second chance. 
The how green is too green is freaking me out a bit, to be honest. Sigh.
