Aspiration pneumonia in puppies

I am in the market to buy a bulldog puppy.  I've had my eye on a particular one for some time now but I found out that at 2 weeks of age, it aspirated while nursing.  One of his lungs was pretty full.  The vets and breeder did everything they could and it lived!  I'm wondering if this is a sign that I should pass on this puppy and wait for another.  Will it be more likely to have probelms now?  Is this the sign of an underlying problem?  How common is it for a puppy to aspirate while nursing?  Most bulldogs have some type of health problem in life.  Is this one more likely to then another puppy?
