Our Airedale could pick the tiniest pill out of a heaping spoonful of wet food. I bet Callie is that talented too!
I wish that I still had the photo from Facebook of the Yorkie who ate an entire bowl of fresh food, looked like stew, and left the pill at the bottom of the bowl. Funniest thing I have ever seen.
Is the pill shooter no longer working for Callie? When we were still using Interceptor for heartworm, I had to put the pill at the back of Teddy's tongue and hold his mouth shut until he swallowed. Sometimes it took a couple of attempts. Putting the pill in food did not help.
