I have been making treats for my rescue Shepard, rolling out dough and cutting, very smallest scoop when I got tired of that. I found a brand new Dog Treat Maker at a Goodwill Store and came home and tried it. I experimented on each filling and will try next time making a wetter dough to pipe in for treats that look like your video... the dog didn’t care that it did not look like a perfect bone, they went down too quickly!
