Two dogs were excluded for high baseline fecal scoring (1 per group); 1 dog was withdrawn in each treatment period due to the severity of her AAGS. Hyporexia, vomiting, and diarrhea occurred in 42%, 83%, and 100%, respectively, of antibiotic‐naïve dogs receiving the placebo. Food intake differed by treatment (F=7.0, P=0.02) and period (F=18.8, P<0.01), with less derangement in food intake in dogs receiving synbiotics. Although days of hyporexia did not differ between treatment groups (P=0.06), it was less common in period 2 (F=4.4, P=0.04). Days of vomiting (F=4.7, P<0.01) and fecal score (F=17.9, P<0.01) differed by week of treatment but not by treatment received. Fecal scores were significantly lower during period 2 (F=9.9, P<0.01).
