Advice on Giving a Dog Pills

Well, Snoopy had her follow up appointment for getting her stitches out after being spayed and her incision site is slightly infected. She did great with her stitches and then all of a sudden she became obsessed with licking it and wouldn't leave it alone. I noticed it getting a little red on Sat. evening, but of course the vet was closed all weekend. I took her in today and the vet said he would feel better putting her in the dreaded e-collar until Saturday and putting her on a 7 day course of antibiotics. I have no idea how to get her to take these pills. Anyone have any advice on the best way to do this? She looks so pitiful with that collar on and I feel so bad for her!

Thanks!
