Ditto on the interceptor. Both of our dogs use it. Sydney happily eats it like a treat, but Gus spits it right out like I just gave him a lump of coal (though Gus would probably eat a lump of coal given the chance!) I just drop it as far back in his throat as I can, then hold his muzzle closed and rub his throat until he swallos. Then I give him a milk bone to wash it down with - works every time. Good Luck!
