Maybe... try it out if you can! I would like to see what happens. It would probably not, although such an experiment would be interesting.
Electrostatic electricity has a big potential - thousands of volts - but small power when it gets discharged, that meaning the potential will subside momentarily to null volts, with the current caused very negligible. This current will cause little harm to the flea, since it consists of very resistive substances. The current might knock over the insect, but won't kill it.
There would be little effect on the flea because it is not in contact with a ground point at the same time it comes into contact with the dog, so there would be no discharge. This is the same reason birds can sit on overhead High Voltage train wires. The charge could, however, pass through the flea enroute to another hair.
The ground principle does not apply where the medium (flea) provides a lower resistance path than the initial one (air). But, again, the low current would probably not injure the flea. *Electronic flea combs convert 3 volts to 4000 volts DC at only a few milliamps, and will at least stun most fleas that pass through the metal teeth.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
