Is there such a thing as Senior Hunt Champion??? Never heard of one. The UKC may have a title which goes in front of the name, SH for Started Hunter, but it should explain that it is UKC, not AKC.
In Great Britain in order to be a Ch, a dog must qualify in the field. If they don't have the field qualification, they are designated a Show Champion- SH CH. This may be true in other countries as well.
Hi..SH.CH. is used in many foreign countries to denote a dog that is a show champion BUT has not taken or passed any field tests. In England a dog has to do that to become a "full" (CH.)champion not just a SH.CH>
