I dont register all of mine just an odd one..It helps when I gift them abroad they sometimes need the paperwork..Price ? LOL If I ever sell then Im probably the cheapest out there average 150 a pop jabbed etc...Plus if I need to check out the breeding its only a click and I can find all I need..It was done in the first place as I wanted to take a few worked dogs to KC shows for a laugh but they banned the docked ones...The benefits the dogs get is a bit of paper saying they cannot work thats borders included LOL LOL
