Our Minature Schnauzer, Grace had a knot on her hip bone. Several days ago it started bleeding a little. I took her to the Vet and was told it is a sebaceous cyst. They shaved the hair around it and emptied it out (yech! Think big pimple). They then gave me an antibiotic, Cephalexin, to give her- 250 mgs, twice a day for 10 days. I am very leery of antibiotics after our 13 yr old Westie cut her paw pad, was put on the same antibiotic and then a month later was diagnoised with cyrossis of the liver. The Vet said there was no way the antibiotic was responsible. Anyway, what precautions or advice do you have for me while she is on the meds. The bottle states to give it with food to avoid upset stomach. Any other thoughts or advice? Thanks!
