Give the vet a call, some antibiotics can make a dog nauseous. If this is the case he may want to change the antibiotic to another.
Also, is she on a NSAID (pain med) those can cause gastrointestinal upset too.
She may be experiencing side effects.
Were x-rays/ultrasounds done? She may need more diagnostic testing, maybe there is something else wrong?
There is an easy way to give a dog a pill, I would ask the vet tech to demonstrate.
They shouldn’t charge for this, maybe you can arrange to bring the dog in when she is due for medication.
Or, youtube may have some “how to give a dog a pill” videos.
Forcing her to eat is not a good idea if she is sick, continue to tempt her and monitor for water intake, add water or plain chicken broth to her food (small amounts of food offered 3 or 4 times a day)
