Our dog, Snickers, has so far been a great addition to our family, and we really love her. She came to us mostly trained and well behaved, but there's been a few times that she caused trouble, chewing up some shoes (fortunately none that were needed) and some toys. I asked some trainers why she was doing that and what could stop her from destroying things, and I was told that based on her genetics (we know she has border collie and lab in her) she's smart, and if she doesn't get enough brain stimulation, enough things to work her brain, she'll make trouble.
I purchased a Kong Wobbler toy for her that dispenses treats if she can figure out how to get them out (in addition to a few other things to stimulate her mind) but wasn't sure what to do about the treats for this toy, since we aren't feeding her kibble, and in general are trying to keep her away from grains (and especially gluten), and just give her a whole foods, mostly meat and somewhat plant based diet. I didn't think the wobbler would work with the wet and mostly raw chicken and fish parts we've been giving her. I needed something dry and small for this.
