Wrap it in cheese. Do I have to solve all your problems? ; )
They just waller it around in their mouth, spit the medicine out and eat the cheese...the same way they spit veggies out of their food scraps. Been there, done that. My one dog has arthritis, so I have to force a Tylenol down his throat on a regular basis as well, for pain, per the vet's instructions...it takes at least 3 tries as he will gag until it comes back up. Any other suggestions?
