Fionn, Im from the UK but have lived in Canada 6 years, it depends on where you live as to the type of work and quarry your terriers get , i think the lads down south should get more work for their dogs, more quarry for starters, ive heard of lads starting pups on Armadillo's and Groundhogs, neither are worth messing with in my opinion, but then everybody has there own thoughts and opinions, they have Grey Fox, Red Fox, Racoon, American Badger( out west) and Possum all of which can be dug the same way they can back home, up here in the great white north they tend to do a lot more barn work,
