Hi Leanne,
It's hard to advise but bear in mind as you don't know what the sire is like, this could grow into a huge dog - what if it was a GSD, Rott, Akita as a dad? Even a Lab - often that cross is regarded as "pit bull type" - so you could be setting yourself up for a very difficult and potentially heartbreaking time. What if the dad was a real nasty tempered dog, and/or had serious health problems - regardless of breed?
Just trying to adopt a Devil's Advocate stance - there are lots of negatives to spur of the moment puppy ownership at the best of times but as I'm dog daft and a soft touch too, I can understand why you feel as you do ;)
Good luck whatever you decide. Teri x
