Lorna terrier

Iv not tried anything yet, I'm from Yorkshire so have no idea where to go down here, I thought if people were going ratting that maybe I could tag along, but any suggestions are welcomed! Really appreciate the responses x

Hello, I have a 5 month old border terrier dexter, who now has all his adult teeth. I want to teach him to rat (altho I have no idea how)! Does anyone have any idea where I can take him where there are plenty rats for him to have a go? Or is there a group where a few people meet up and take there dogs ratting... ?? Any form of information would be massively appreciated as I'm not from the area and have never had a dog before so have no idea at all where to start... Many thanks!!
