Answer:
Well, it really depends. You have to look at their pedigree and find out if anyone in their family has long hair. Such as the grandpa or grandma. 2 short hair dachsunds had 4 puppies. 3 were short haired and one was long. Their next litter was 2:2 and their last litter was 2:2 again. The dads parents both had long hair.
