This LickiMat Slomo for Dogs ($14) is a good pick if you're trying to get a dog to eat slower (and the anxiety-reduction is an added bonus). The two quadrants with larger holes can serve up kibble and wet food can be smeared in the other sections as a mealtime bonus. Or, I especially love this for a special treat with blueberries in the larger holes and soft human foods like pureed pumpkin smeared in the other two.
