skin or soft tissue infection
"The vet gave this antibiotic to my mastiff when she suddenly had welts raise up all over. He thought she have been stung or had some other type of introduced infection. So far so good, but it seem to give her a bit of urinary incontinence. She has had that before whenever she takes any antibiotic. She is taking other medicine too, so it is hard to say which one is helping or causing the side effect."
