Yes, and the result will be another piebald dachshund litter.

Of course you can. Piebald is a colour variation.

Piebald is not a cross breed. Two dachshunds bred together need to have the piebald gene in their background. Piebald is recessive and will not show up but you could see a relative that was a piebald in the pedigree. Two piebalds bred together will produce all piebald puppies.

Piebald is black splotches, skewbald is brown splotches.
