There is an obvious reason why even a dachshund living on a farm would climb anything whatever.
Dachshunds are earthdogs [which is what terrier means]
and they are bred to hunt. Just because they are named for badgers
doesn't mean they would turn up their long noses
at smaller vermin!

Sure, dachshunds are better at digging than climbing,
but try reasoning with a dachshund
who just spotted something small that smelled like
it ought to be chased and hunted ...
