if they will eat it straight up crush or mince it and mix it with food. offer no foods at night and offer foods with the garlic first thing and wait till they have eaten it for 2 hours before giving non garlic food to ensure atleast some garlic has been consumed, otherwise you could heat chopped cloves in water and simmer for 30 minutes and strain and just offer garlic enfused water instead of food
