Help needed....

Hi all, Stevie may is now 10 months old and she's started chewing/eating the WALLS!! she has a room downstairs which she sleeps In and goes in if we pop out.
is it boredom or she's not got enough toys?? or rebelling

i would very much like your help and feedback please, if she carries on like this i'll have no house left :-(

I'm sorry I can't help much as we crate trained Skye from the day we got her although she did manage to chew a few chair legs
Buster was also already crate trained when we got him

Dempsey was also crated when he was left, & overnight.

Have you tried wiping some Vicks over the chewed surfaces?

It's boredom frustration most of the time.. Mine's started chewing side walls when I leave the house but I've sprayed some dog chew spray and I think he's stopped.. I've heard of dogs doing this up to 14 months old

How much time is your dog active(walks+games)in time?

Sounds like either boredom or seperation anxiety. How much exercise is she getting?
