Urine showed the bacteria to indicate that he has a UTI. I also noticed that after a week of metronidazole he still has some loos stools. I have him on amoxicillin. I am going to see if this helps and if not I will then try the cephalexin. I had the amoxicillin on hand so I figured why not give it a try. Let me know your thoughts. Also a question for Jack: Why is it you would recommend cephalexin and not amoxicillin? They both seem to treat the same bacterial infections. Amoxicillin is even used to treat UTIs.

Thanks in advance?
