One thing that might help keep your pup from chewing the furniture and carpet is Bitter Apple. It is a spray that you can get at the pet store ... you just spray it on your carpet and furniture and it makes everything taste really bad. So after your pup has a taste, he won't want to chew anymore!
Although some pups LOVE the taste of it!!
Bear thanks me everytime I spray something with it, as if to say "Thanks Mom, it tasts
so much better now!!!"
So far, I've found having tons of different toys around: ropes, squeaky toys, soft toys, hard toys, toys with bumps, and squiggles, balls and anything else you can think of. When pup starts gnawing on something he's not supposed to, pick up a toy, make a big fuss over it, like there's nothing on earth that is better than it, and soon he wants it from you.
The crate! Thank the dear Lord above for the inventor of the crate. This is a great place to put him, along with several chewable safe toys.
I also use rawhide rolls, not the bones, but the ones that look like ladyfingers. I find he's able to gnaw at these better, especially when he was younger.
It takes some time, and lots of patience, but they do finally get the hint that these are GOOD chewables, and these are BAD ones. Good luck, and welcome!
