I have the most pill-hating greyhound on the planet

I tagged this advice but I feel beyond help, lol, sob. Has anyone else ever had a greyhound who refuses all the pill tricks you've ever heard of?

I'm nearly ready to ask a behaviorist for help because I wonder if the problem is more a matter of dog psychology than finding a tasty enough treat

I have tried all the standards of cheese, peanut butter, tasty meat, cream cheese. I've tried untraditional ideas like hiding it under some drained canned tuna.

Somedays something works, yet it's usually a different thing every time he has to take a pill which is twice a day. Helppppp

Edit: he finally took some pills in bologna with gusto. And then just to let me know who's boss he then ate the cheese he wouldn't even sniff an hour ago

commiseration still welcome

Edit 2: I've received so many amazing suggestions, so many creative options. Thanks y'all, this is gonna be fun for both human and hound to try some new ideas.
