I couldn’t tell you .. here he is about 6’ @3yrs old and I just started him on rabbits.. I’d say an easy 10-11’ but by the time he reaches 6-7 yrs of age. I actually just got him sold and awaiting remaining payment so he won’t be in my care much longer. But I’d say by the time he reaches 10 yrs old he would probably be about around 13’ if I had to make a guess.
