my dog tested positive for lyme and kidney problems. her creatanine level was 3.0 and bun was also high. there was no protein in her urine. My vet recommended a 4 week course of doxy which she has completed. She is doing well, eating, playing, and interacting with us. What is her prognosis? I am unclear what to expect going forward?

Hello, While we know that Lyme disease can cause kidney disease, we cannot assume that the Lyme disease is causing kidney injury in this case. Many pets will test positive for Lyme disease on a screening test if they have been exposed to the disease. However, exposure does not equate to clinical infection in every case. In order to determine if Lyme disease is causing kidney injury, we need to measure antibody levels in the blood, ultrasound kidneys, and obtain a kidney biopsy. Without this information, it will be difficult to give a prognosis. I would advise you to follow up with your veterinarian to discuss recheck kidney values, abdominal ultrasound and urinalysis.
