Please Help with my German Shepard
My 100 lb German Shepard is on 10 mg Prednisone every other day. She is taking it for Allergies and is now unable to pee, she does pee and poop in her sleep. She is straining to pee and poop every few minutes. She is 5 1/2 years old. She started not being able to poop when she was on osteoarthritis medicine. Now she lost too much weight on that medicine and doesn't take it anymore. But she still is straining to poop and not able to pee. Her Poop was tar black over night and would love some help with this matter.
