Harness Goat (potential) - $400 (Sekiu)

OK hear me out on this lol I have a Goat that has decided to start jumping all of my fences lol they are only 30 inches tall but she wants the stuff on the other side so I am going to butcher her.
My wife is making me make this post because she is a pet, she is a pocket pet but she keeps escaping And she is living on a tether and that’s not OK.
but she has tremendous potential as a harness Goat.
She has an absolute lust to pull.
She doesn’t do it uncontrollably that’s what’s awesome about her I can lead her left and right pulling logs and stuff behind her but I just can’t get her to stop she doesn’t runoff but she just wants to go and go so she would be an absolutely awesome harness Goat to somebody that knew how to train  and on a sidenote she is in milk
