What do you use to mask the smell/flavor of supplements?
Texture - need some kibble in it to fool the mouthfeel of pills
Aroma - little garlic powder, parmesean cheese, italian seasoning
Taste - rotate meats and the aroma stuff above adds flavor, rotate olive oil with coconut oil.
Tempurature- dogs respond to body temp food. I add some warm water to bring out aroma and flavors, plus dogs are predatory carnivores and need kill temps for best eating stimulation.
Some dogs have aversions and preferences to keep trying combos and keeping log. Don't put too many pills in right off, just keep adding over a few weeks so dog doesn't hate the meal and randomly give a day or a meal break from pills so dog does not get food aversion.
Veggies, they help the tastes and aromas as well. Lucy gets either canned carrots, green beans, chopped canned spinach, a bit blueberries, sometimes raw carrots which if your dogs mouth is ok, will help clean teeth and freshen breath.
