A Dog....O.o; that jumps?
My dog doesn't.
The quick brown fox jumps over the lazy dog. The five boxing wizards jumps quickly.

It depends on how high the voltage is, if its too high it can do nerve damage, seizures, etc. to the dog. The dog should not be injured by the electric collar, just feel the waves enough to get the dog to stop what hes doing.
An electric fence does not prevent a dog from jumping over the fence. The only way to prevent a dog from actually jumping the fence is to build the fence high enough to keep the dog from being able to clear it when he jumps.
