As long as we're dealing with statistics here, I think I should mention that approximately 95% of male dachshunds will enthusiastically mount just about anything, male or female or even inanimate, when they are in the mood which is...frequently.

The remaining 5% are too lazy.

It has not been determined if this indicates homosexuality in dachshunds...or merely a complete lack of discrimination. The jury is also still out on whether it's a primarily genetic feature of the breed or a form of learned behaviour. Some researchers feel that it all stems back to a single bloodline of licentious dachshunds bred by the Baron von Bumpsenhausen in the early 1700's, but this remains speculative.
