With my shih tzu, I finally found a way, he is a smart dog and mean if he starts freaking out like trying to force his mouth open, he is a street dog rescue.....but anyways whether its pill or liquid I wrap it in the middle if thin slices lunch meat like Turkey or ham put it in the middle like rolling a cigerette and roll it up, they can't smell it, and he smells first he only smells the meat....I tease him with it a couple times then give it to him. You know how dogs will scarf up food they love.My cats I am still able to open there mouth.

With my Shih Tzu, I finally found a way; he is a smart dog and gets mean if he starts freaking out, like if I'm trying to force his mouth open; he is a street dog rescue. Anyways, whether it's a pill or liquid, I wrap it in the middle of thin-sliced lunch meat, like turkey or ham, put it in the middle - like rolling a cigarette - and roll it up, they can't smell it, and what he smells first is only the meat. I tease him with it a couple times, then give it to him. You know how dogs will scarf up food they love. In case of my cats, I am still able to open their mouth.
