Holiday treats for our four-legged friends?

I've never met a dog who didn't like peanut butter. My pooch has Lupus, so I have to give him meds every day - he eats them out of my hand, as long as they're encased in PB. (Of course, he's a Lab, so not particularly discriminating in his food-related enthusiasms.) At the end of her life, our last dog suddenly became finicky about what she'd eat; again, peanut butter was the preferred (only) med delivery system. Clearly, dogs love the stuff.

For our horses, I made "Nicker Bars" molasses, whole oat with shredded carrots. Just dumped in oats, and molasses and flax seed, shredded the entire carrot ( including the green tops) bake on parchment paper. Low at 250 for 20 min.

My dogs don't eat grains and I have been thinking about what kind of treats for the holidays. This is an excellent question. They love peanut butter so thought that I might take natural peanut butter, mix with some almond flour and grated carrots and make little balls (like fudgy bourbon balls) For my diabetic dog I was thinking of doing something with baked chicken livers run through the processor and add ground raw veggies press into a mold (like a loaf pan) so it resembles a pate.
