Just for referance, here is a pic of him in his halter the first time I put it on him (he was a little more than a month old).
And now, here he is yesterday in the same halter . It is in the last hole and I could hardly get it on him. The nose is way too small for his big honkin' head.
I managed to catch him snoozing too.
So now he has graduated to a full size horse halter since that is all we have.
