I need to ask a couple questions first. How much does your dog weigh? why was she being treated with the antibiotic and the steroid?

I am a user of this site, like yourself and have nothing to do with charges. It sounds like they started antibiotics because her lymph nodes in her neck were enlarged, but did not show improvement until they started steroids. The steroids can cause urinary leakage in some dogs because they will drink more water than normal. If it is due to the steroids and you have stopped them then the leakage should improve over the next couple of days. The thyroid medication does not typically cause urinary issues.
