I know it works, but why does it work?
Seems to me giving them a toy would be in their minds like, ok so your chewing on me or something I don't want you to chew on so here is a treat!
Like we are praising them for chewing. Lol sorry if this sounds dumb, but it is a question that stays in my head when I do this :)
Why do you all think this works? I have no idea to be honest but thought I would throw that out to see what your opinions were on this.
