I just yesterday tried the spray bottle trick to get the pup to stop chewing on a box. It works great (and its fun! ) But can I say NO! at the same time? I'd like to eventually have them understand NO! a bit better in case I don't have a bottle around and I think that would help.

I use NO! at the same time but I never thought about whether or not I should or shouldn't. I don't think the NO! part has sunken in yet.
