This study aimed to evaluate fecal characteristics of dogs fed three diets: control, supplemented with 0.10%MOS and with 0.25% aluminossilicate mix. Fifteen adult Beagle dogs were used. The trial followed acompletely randomized desing, in split-plot, with five days of sampling collection and five dogs feeding eachtreatment, in a total of 25 observations per treatment. Diets were offered for 25 days adaptation periodfollowed by a five days total feces collection period. Tukey-Kramer’s test was used to compare the means.Dogs supplemented with aluminossilicate mix in diet had higher fecal dry matter content (40.40%) and higherfecal score (4.00) than the other diets. The supplementation of MOS resulted in medium dry matter content(35.72%) and fecal score (3.64), while dogs fed the control diet showed lower fecal dry matter content(35.72%) and score (2.84). The concentration of ammonia was lower in feces of dogs fed diets withaluminossilicate mix (0.30%) or MOS (0.30%), than on the control diet (0.35%). The diets did not differ aboutpH and fecal output. The inclusion of aluminossilicate or MOS positively influenced fecal quality of dogs.
