I was asked the other day how to stop a puppy from chewing...the short answer is YOU CAN'T ..... BUT you can work to resolve destructive chewing. First we need to remember dogs chew because: they are bored, they like the taste/smell of the item or they are teething ....my first motto is this .... "do not set the dog up for failure "... So you need to do your part.... Remove temptations from there area like garbage cans with great smelling trash, leather shoes etc.... Then limit there area.... You can even crate for short times if needed....my favorite area is a small fenced area in garage that has a dog door to backyard or play area or outside kennel etc....then stimulate the brain,,, entertain them.... With special toys or good solid chew bones....you can "refresh" there toys... Like I used to once a week go collect all the rope type toys and boil them in broth....chicken, beef, whatever... Let them dry overnight and when you give them back....it is like a new toy.... Also before you leave the pup for a period on there own.... Get them exercised.... Nice walk before leaving for work, or some fetch.... Get them tired.... If you have a high energy dog - and you are gone several hours a day... Look into a dog day care..... Remember set them up for success!!!!!
