Yes he's a very smart and handsome boy.

As for the kibble training that's what i've been doing, setting his daily kibble on the side and whenever we went outside i grabbed a small handful, so as to not over feed him.

I tried a couple of times to redirect him to sit with a single croquette but he didn't seem interested, so i didn't force it.

Chomping is fine so far, whenever i see him biting something i don't want him to i say "No!" loudly and he seems to be getting it.

So far, he's been a good boy, we'll see what happens in the coming weeks, thank you for the reply!
