My previous sheltie Buddy only chewed on kleenex and toilet paper , nothing else. I had no idea how lucky we were that he was not a chewer.
Now for 9 month old Bailey.....everything
Shoes seem to be his favorite, baseboards, the chips in th bottom of my plants, coasters, my computer cord, cat toys ( mutulated), carpets, not to name paper, toilet paper, kleenex etc...!! Anything that he can find, he chews. Outside its leaves, sticks and any garbage he grabs before we can yell "LEAVE IT"!! He tried chewing on our good dining table & chair legs once & he was yelled at quite abruptly & it scared him ,he hasn't tried that one recently.
His shoe fetish

is much better probably because we hide all our shoes & if we catch him we yell NO!! at hiim. We sprayed the carpet runners ( at the edges where he was chewing) & the baseboard corners with the bitter no chew spray & it has been much better. We just have to warn anyone that comes to our house to hide their shoes & don't leave any bags or purses laying around on the floor !!
I think he is actually getting better because we are always yelling NO or LEAVE IT! at him & he is starting to get it. He loves his chew toys so I make sure there are plenty on the main floor ( which is the only floor he is allowed on right now) I have bought many chew toys for him & make sure I stuff one in his mouth when he goes for something else
Let's hope this settles down soon, he has ruined 4 pairs of my shoes so far :-o
