Dogs & pills....

Peanut Butter.

I use to put my dog's pills inside a spoonful of peanut butter, on the tip of my finger, and scrape it off behind her front teeth on the roof of her mouth. She loved peanut butter, and never once rejected the pill.

Cheese works well, too. I'd use cheese as a change a pace for her. It was just as effective.

The dog seemed to think it was a treat, as she would come right to me and sit in front of me wagging her tail and readily take the peanut butter or cheese. Never had to force here to take it, ever.
