The effects of supplementation of two probiotics to puppies fed two diets - high and low quality - on nutrient digestibility, faecal score, and blood parameters were evaluated using 18 animals in three treatments. In the treatment 1, control, the dogs received only food; in the treatment 2, food with probiotic 1 (Bifidobacterium) and in the treatment 3, food with probiotic 2 (Lactobacillus). The research was divided in two phases. It was verified that crude metabolizability energy coefficient average values in the phase 1, characterized to changing Super Premium food to Standard, presented significant results (P<0.05) and the best ones were obtained in animals that received the probiotic 2. No differences (P>0.05) on faecal score and blood analysis were obtained.
