The present study represents the first investigation of
the prevalence of weaning diarrhea in puppies living in a
breeding kennel. Prevalence of this clinical sign, affecting
both growth and survival was high with 24.8% of puppies
between 5 and 14 weeks concerned. Among the seven different
enteropathogens (2 viruses and 5 parasites) tested
in this study, 77.1% of puppies were infected by at least
one virus or parasite, and 55.3% carried multiple organisms.
Prevalence of parasites was higher than the prevalence of
viruses (74.4% vs 34.6%).
