Interesting analysis and in fact I see that bookmakers estimate the probability of Dortmund winning as low (less than 50%):
3.45 - 3.55 - 2.12
I’m not sure that the bet on Freiburg is justified, since the odds are not so good - only 3.45, and the game could end in either a draw or a victory for Dortmund. Maybe it makes sense to bet on Freiburg Double chance with odds 1.70.
I think Freiburg has good chance to win this one. Dortmund are very poor in terms of goal scoring right now. I feel if Freiburg manages to score 2-3 goals then I don't think Dortmund have a chance to win or draw. I also agree that Freiburg and double chance seems to be a very good bet here. It's gonna be a good shot as Dortmund has really let down so far since the start.
Even Bayern will have a hard time winning if they concede 2-3 goals first

although they often concede 3 goals after leading 5-0 or something like that. In fact, this will be another random match from Dortmund and I don’t know what bet to make is more correct, maybe it’s even worth making a live bet or just passing by this game.
