Fig. 3

Fecal E. coli susceptibility over time. Percent of MDR-E. coli at different time points are shown in panel A, with total percentage of dogs with any E. coli cultured in white, and MDR-E. coli shaded grey. Panels B through J depict susceptibility for the individual antimicrobial drugs tested. In those images, the white boxes also indicate the percentage of dogs with any E. coli, and the shaded boxes indicate the proportion of dogs with resistance to each respective drug as labeled. Statistically significant differences (Exact McNemar test) are denoted by symbols *P ≤ 0.05 and #P ≤ 0.01
