They were bred as badger hunters, not exactly decorative.

That's a valid point, but do we need badger hunters this day and age? Perhaps go back a couple of centuries before they became so deformed?

This goes for (almost?) all dog breeds. Most of the working dogs of the past are now kept for different reasons, if you apply that kind of reasoning you will likely get rid of all dogs, especially purebreds because they all have their share of problems, some more than others.

Yes. And people buy blue sweaters and many other colours when it is clear that no dye is better. Simply put, the demand for dyed clothes should not exist.

Welcome to capitalism and the free world. Sometimes we just need to be tolerant of others and let them get on with it.

I'm not against viable dog breeds but Dachshunds suffer many disorders/congenital diseases that make their lives miserable just to please their owners and here we have someone further enabling this.

Blue dye on wool doesn't harm anyone. Even the Soviet Union a totally non-capitalist country allowed colors, so I don't know what your point there is.

You know what makes life really miserable? Not every having life, due to not being born.

Maybe you should ask these dogs; would you prefer to have never experienced life at all?

(Basically, I wonder how miserable they are. They seem happy when I see them.)

Not being born is only a problem if you had the notion that your potential life was cut off. A potential zygote, not an exiting zygote, obviously has no cognition by definition and by determinism. So there is no suffering. Nothing is being aborted. In any event, if this "dog x" has to exist, why not a healthier crossbreed?

I'm not proposing to cull the existing dogs, just not to further a breed and other breeds of dogs that suffer health problems due to our artificial breeding. There are lots of other dog breeds that do not suffer more health problems than average.
