Well she already has heart disease and has to take medicine and some aspirin for her heart, but the vet said she might had some hemmorageing in her kidneys (because she hurt her side jumping on the refridgerator) and she had some bleeding in her urine. So now we give her amoxicillin for a week or two to help with the infection and we feed her Science Diet c/d food, but she has been having diarrhea for a few days since starting the medicine and food. I think it went away, but do you think its from the medicine or the food? She seems to be acting okay, because she still is her normal self though.
