Where is the Dog's Bark Collar

Duke the yellow lab now has to wear a bark collar that we take off at night. For some reason I had to put it on the Golden Retriever who has long hair. Next day, Sat, I can't find the collar. Damn kids I blame but still no collar. I check to make sure I had taken it off Duke, no collar. Sunday all day looking, no collar. Monday no collar, wife spent a day looking. Monday night I am out playing with the dogs and there it was on the Golden retriever. She has long hair and anyone in my condition could have missed it. I still maintain with the wife that I took it off and one of the kids put it back on. Damn kids, Sigh.
