My puppy's favorite toy is my wood bed frame. I've placed vinegar on my electric cords and on the bed but she seems to like the taste. Any other suggestions?
There's another technique involving lemons that requires more than just spraying the object and hoping for the best. The dog needs to associate the bad taste with the object being chewed. With the dog right next up close to the bed frame, squirt a little lemon juice into its mouth. Then rub the wood with the peel (lemon oil from the peel is especially bad tasting). Tie the dog's leash up around the frame so the dog is sitting very close for about a 20 minute timeout. With the smell of lemon on the wood, the dog should associate it with a bad taste in his mouth. After the timeout, give your dog a choice between the wood and an appropriate chew item, like a bully stick. See how that works and repeat.
I have always used Bitter Apple or Bitter End sprays, but you can also try hot sauce or hot pepper.
You might also want to try wrapping the legs in something like foil or inside-out packing tape to deter chewing while you provide lots of appropriate options, and of course restrict her access to that room when you're unable to supervise her. Rotate out her toys frequently so she doesn't get bored with them.
This might sound weird, but it's the most effective anti-chew substance I know of: Arid XX antiperspirant solid. We used it in one of the vet hospitals I used to work at to keep dogs from licking and chewing at their IV catheters. I also used it on my kitchen cabinets when my puppy was chewing on them. She loved the taste of bitter sprays -- I could squirt it directly in her mouth and she would ask for more, lol! But the Arid worked. Just smear it on your bed frame and the electric cords. BTW, if at all possible, put as many of the chords out of reach as you can; I wouldn't want her to get electrocuted. Also make sure she has toys that she can chew on, like Kongs or similar.
A product called "Bitter Yuck" works for me. I spray it on the wooden table legs and on computer cords. Just be sure you wash your hands afterwards....it really is an unpleasant taste/odor, but it's not toxic.
I would use a ecollar an correct that dog ASAP. A small one or two time correction is better that a $3000 vet bill.
