I don't really think that docking the tail can be justified just so that people can tell the difference between the two breeds. there are so many ways to tell the cardi and the pem apart, maybe people just need to be educated a bit more to recognise these differences.
Reasons such as tail injuries, back-problems or hygiene are different.
But I don't think we can fight to remove the tails of these dogs purely because of the way we want them to look.
Here in Australia, evidence of tail injuries, hygiene issues or back problems in tailed corgis is very few and very far between.
Obviously this is an issue that everyone is passionate about. It's hard to find someone that doesn't have an opinion about it. It is hard. I have no doubt that we all love our corgis. It's hard not to.
They are the best breed of dog in the world.
Would love to hear other peoples opinion on the issue.
