When my dog was a puppy, she used top chew on everything(and sometimes does now) including: sofas, headsets, erasers, beads, wire, rubber stoppers, cables, and even tried on my cat! We had to think of ways to get her to stop eating and chewing on these bizzare items. We used the "Chewie/Fetchie" system(I will explain later on) and used something like a can of beans or marbles to get her to stop before she starts. A spray bottle always works great for scraching on sofas or leather furniture(We only have leather). You need to zap them in the act with only a little water. That just freaks them out a little and they may back off for a while. Bitter Yuck or Bitter Apple work great for plastic items on the ground that your dog is causing distruction to. We use Bitter Yuck for my dog and it works great! She hasn't chewed on that box for at least a year! My dog is a great indoor pet, she can't go outdoors, and behaves really well besides her barking. Barking is probably one of the most commen problems. She still barks a lot today, but less. We thought maybe if we had scolded her more when she barked when she was a puppy, she would hardley bark at all. But we can't go back in time can we now? If anybody has anymore tips about how to resolve puppy problems, post here. And take the poll, it may help if you have puppy problems.
