Dog Health Questions: How can I get my dog to stop chewing up everything in sight?

I have a 6 month old papillion...he is unruly, the worst dog in behavior I have ever owned. He even hops up on the dining room table. He is horribly naughty. I need some pointers in dog training nothing we do is working!

Dog Training - Beyond Conditioning

Recommended Answer:
It is known that many canine misbehaviors are born out of instinct, and most arise from either boredom or stress. Aggressive behavior, chasing, marking, and resource guarding are modern manifestations of dogs' early instincts to acquire food and protect their territory and pack. Digging and chewing, on the other hand, are usually the results of boredom.

Basic Dog Training Commands

• i can't help w the hopping on the table because my dog does that and we have to turn the chairs around but the chewing on stuff; there is a product called bitter biter and it tastes VERY bad that will work w some now my dog got used to that but she does not like the taste of vinegar water mix i spray on this carpet she just can't get enough of and that worksalso one thing that is GREAT for potty training is we put bells very low by the door and rang them as we took her out each time and in 2 days she learned to ring them herself and now has no more accidents in the house
