Pet's info: Dog | German Shepherd | Male | unneutered | 10 years and 9 months old | 95 lbs
Our 90 lb German Shepherd is on 1000mg of keflex 2x / day for 21 days. He was put on it for a severe UTI. Is this to long of a duration for the med ?

In cases of severe UTI, this is an appropriate length of treatment. In some cases, treatment may go for 4 weeks or longer. As long as the bacteria is susceptible to Keflex (cephalexin), this should resolve it. It is important to perform a culture and sensitivity on a urine sample after treatment to confirm resolution.
