In my experience, it's a matter of teaching them what they can and can't chew or use as a toy from day one.
They learn pretty quickly and it's job done. I've never had to deal with furniture or cables etc getting chewed.
Obviously, some breeds are more prone to it and it really helps if they're not left bored out of their minds for extended periods.
Yeah true.
Fwiw my labradoodle (pictured above) hasn't really bitten any furniture and he's 16 weeks now. (had him around 8 weeks)
Just give the dog lots of toys to play with
