FIGURE 1.

Fecal dysbiosis index of dogs age 1 to 2 weeks (n = 14), 3 to 4 weeks (n = 14), 5 to 6 weeks (n = 13), 7 to 9 weeks (n = 17), 10 to 16 weeks (n = 11), 20 to 48 weeks (n = 11), and adult dogs (ie, dogs >52 weeks of age; n = 13). Dysbiosis index was significantly increased in dogs age 1 to 2 weeks, 3 to 4 weeks, and 5 to 6 weeks (P < .001 for all) when compared to adult dogs. Dysbiosis index was not significantly different from adult dogs at 7 to 9 weeks of age (P = .05), 10 to 16 weeks of age (P > .99), and 20 to 48 weeks of age (P > .99). Red lines indicate medians and red asterisks indicate significance in comparison to adult dogs (P < .05). Dark shaded area (values <0) represents reference interval, and light shaded area (0‐2) represents an equivocal range. wks, weeks
