Right now I am having to give her 6 or 7 pills a day (her antibiotic is cut into four -1/4 pills because it is too large), and she fights me really hard for the last three or four. She hates the liquid Iron the most.
I'm glad that Sydney is still managing well despite all that she has gone through. She is quite a fighter that girl!

You might want to see if you can get the tablets you are giving Sydney crushed up into a suspension by a compounding pharmacist in a palatable flavour like chicken or seafood. Then you could maybe sneak it into her food that way?
What kind of antibiotic is she on? If it is in the Clavamox family, you could ask your vet if she could be given the Convenia injection. It is equivalent to 14 days worth of clavamox tabs but is given in one injection. It may not be suitable for the kind of infection she has though.
