I think it depends on the extent the "help" goes to. If it is just a fitter coming in to help with show day preps, clipping, coaching, etc...then no I dont think it is at all a problem...but again I may be biased because I will be one of the ones there doing that. But if it is a situation where the parents have paid the fitter, the fitter has raised the calf, the kid has only seen it at shows, the fitter hauls it to the show, and you never see the kid anywhere around the calf until the calf gets to the gate of the showring, then in the Jr shows yes I have a problem with that.
Now in the Open Shows...I say its all fair game...the open show is about a breeder marketing their product, so if they hire someone to market that product for them, then so be it.
