Our 1 yr. old Golden, Payson has Lyme Disease. He was vaccinated, had booster, and wears Preventic collar; He went lame on front leg in early spring and was OK in a day--4DX (-); he again went lame on same front leg in August and was (+) for Lyme; He has been on Doxy for three weeks and we will continue for 6 weeks at a higher than recommended dosage. His test showed no protein in urine;C6 test--we were not told to go this B4 treatment was 732 after 4 wks. of Doxy. So we have no real baseline. For those of you who have gone through this, does this high number have significance other than a big antibody response is being mounted? If we do C6 in 6 mos., if result is half 732, do we assume treatment was successful? I know we have to continue to test. Can anyone help? He is our 3rd Golden and we have no experience with Lyme. Lyme is rather new to southern PA and vets do not have much practical experience here. Thanks from Payson!
