You can get some Critter Cord... of spray it with Bitter Apple....
Riley got electrocuted when he was a tiny puppy. I always watched him like a Hawk.... Well I had answered a phone call and had been on the phone, not even 2-mins. and he had slipped under the tv stand and behind the tv. He chewed right through the cable box cord. I head a loud pop and he came running out, SCREAMING and looking very very terrified!! Once I finally was able to get hold of him and calmed him down I checked him all over.... he was doing a cough/gag type of thing.
I ran him to the vet and they said he was very lucky!! A lot of pups are immediately knocked unconscious, or dead.... and if not, they can develop water in their lungs... which is really really bad!!
Riley was totally fine!! I did order some crittercord but he hasn't gone near a wire or cord since.
