Funny that dog went for the Fluke meter, i lost set of leads to a new puppy here myself, she jumped up and pulled the leads off the bench and chewed the ends off, i had it set to continuity testing when i walked away and i started hearing this beeeeeeepppp... beep... beeeep beeeep... Looked back and that little SOB was chewing the leads off... Thankfully the meter wasn't damaged, a new set of leads for $30 and it was kept tucked away back farther on the bench from then on.
Funny i see the extension cord was mentioned... I had another dog years ago that was on a tie out next to the house one afternoon and i was having dinner and the tv started getting fuzzy then went out. That stupid dog chewed through the coax! So i moved her to the front yard and fixed the damage by running a new cable and replacing the end of the drop where it came out of the ground, was in the middle of winter and digging down to get to good cable to make the repair was no fun!
About a week later i put out christmas lights and as it started to get dark i noticed they weren't on, they were plugged into a timer. I went out and sure enough that stupid dog pulled the cord out of the timer and chewed the end off. Well i fixed that and again tied the dog in a new spot. Then she started to chew through her tie out because there was nothing else. I was fed up... I took a black extension cord tossed it across the lawn, plugged it into a NON-GFCI outlet and walked away. Two hours or so later i heard the most disturbing yelping and screaming like sounds from the front yard, stepped out the door and the dog was jittering around on the cable mouth clamped down, i unplugged the cord and she crawled away and hid under the picnic table in the front yard for about 8 hours before she came out. After that, no more chewing problems period...
I think all dog owners have their chewing stories! I also had a dog once that was left upon me, it was a 





of a dog, about three days later he went "missing" also.
