We have a 10 yr old labrador retriever, named Pushi, who is diagnosed with kidney failure with E. Canis detected. Her blood report is as follows : UREA 149.00, BUN 72, CREATININE 3.80, URIC ACID 2.48, ALLKALINE PHOSPHATE 311.00, Hb 9.2, RBC 3.1, the remaining components are within normal ranges. We have consulted our Vet who has prescribed Enrofloxacin for E Canis. She has stopped eating and thus is being given ringer lactose and normosol saline alternately everyday. A lot of occult blood was observed along with her stool due to which a haemocoagulase injection was being given. Its been 2 days since we have started giving Rehmannia 8 but we are not being able to find the correct dosage for her. She is 40 kilograms(88 pounds) and we are giving 6 tablets of 650 mg per day. Kindly advise us whether the dose needs to be corrected or not and also give us other suggestions.
