He should tell you anything he finds that he's concerned about, that's the point of it he'll probably ask you if there's anything in particular you want him to look at (conformation, a lump on his leg you're not sure of etc), so just let him know if there is.
I had to ask the chap who vetted Barry if he'd actually passed him!
Well he passed the vetting with some issues which we were expecting, mild arthritis in one hock, he also said he was slightly lame In the off fore leg after the flexion tests, he's also a bit light in weight and seems very tucked in and maybe could be teeth issues but he's eating fine and has been on weight gain for 3 weeks now, the horse got quite upset with vet when he was checking his heart and tried to kick his hand, not sure why but he's been great every time we have visited him him.
Hubby's very confused, as he thinks he shouldn't of passed the vetting if he's showing lameness .
I agree that most older horses would "fail" a flexion test but pass as fit for purpose, the flexion test is a fairly crude way of checking for signs of problems they are only a small part of the overall assessment. The kicking may have just been due to the horse being unsettled, many horses get stressed by vettings it is fairly intense and at times a little painful, flexions are uncomfortable to say the least, a little out of character behaviour should be forgiven if he was generally good about most of the procedures.
I think flexions can be a bit hit and miss anyway - I had a 5 year old fail on flexions but took a punt anyway, he's never had a days lameness in his life! At 18 you would expect some minor issues, hope it goes well OP
