She could have dal in her. But it wouldn't be one of the first guesses I would make. I had a dog that was (all of these were papered dogs, so we knew for sure, she was the product of two oops litters) 1/2 weim 1/4 bouv and 1/4 lab. She was a dead ringer for a black weim. AND very weim like so if someone dropped her off and said she had dal they might be right.
But from looking at pics I wouldn't have thought of it unless you mentioned it. it would be interesting to see her move, I find dals have a very light effortless trot.
