When he was a pup he chewed through a lamp electrical cord. We took him to the only 24 hour vet hospital. After a few hours they said he was fine, he had had none of the problems that can come from electrical shock.
Who knows, maybe?
well I Dont know....
Duke, the Newfie, has chewed through a lot of things electrical in nature but doesnt do that either...
I think its just the dog's personality....and that sucks too...Shepards can be great dogs
