Toby has never destroyed anything, but then again he was crate trained, so that keeps damage to a minimum....
Toby doesnt bark excessively at all, he is a very quite terrier actually
he growles when peole are outside our apartment, but it isnt loud at all, he is very pleasant that way...
As far as nipping, yes....... he does this, BUT we are constantly telling him "no" and not playing with him if he does this, and he has now learned when not to nip and when (during playtime) it is kind of ok.........
