Sorry to hear Penny's poorly. A trick a vet gave me once, was to open the mouth, and drop the tablet on the back of the tongue, hold the mouth shut again and stroke the dog's throat in a downward direction. It obviously depends on the dog and how comfortable she is with you handling her, I certainly wouldn't force it but it used to work with my old dog, who would eat the sausage and then spit the tablet out!!! After a bit of practice, it was a pretty quick procedure but if you can get her to take banana or something similar, better still!! Best of luck, hope she's better soon!
