The French can’t swim.
This is done on a case-by-case basis, however, the French carry 85% of their weight on their shoulders, which makes them heavy as high as possible. While French people like @cheriethesurfdog are fine in the water, don’t try to let a Frenchman near the water without a life jacket if their swimming skills have not been proven. The French are known to sink like a rock, which is why a dog life vest doesn’t sound so funny, but it’s necessary.
The French are not very good guard dogs.
There is a joke that the French are not good guard dogs because they think they are all there to be caressed.
If you haven’t seen it, Frenchwoman Jules wants you to watch a movie in which she defends her home against… bears.
