Being new to sheep and all there is to learn, I have found pronouncing the name of my Zwartbles one of the most challenging tests so far! The breeder calls them 'Shwarbles', the vet calls them 'Zwartbulls', the shearer calls them 'Zwarbles'and a neighbouring farmer calls them 'Zwerballs'! Each one laughs at me if I accidentally call them by what the other person calls them. So I have given up and just call them 'The Zeds'!
