Kidney biopsies from representative dogs and mean interstitial fibrosis scores (score range: 0 [normal] to 3 [severe]) for each group of affected dogs at 3 time points (T1, T2, and T3). Fibrosis scores were based on evaluation of multiple 20x fields. *Statistical significant. Scale bar: 100 μm. (Trichrome-stained).
