The review by Qing Yang and Zhenlong Wu (2023) examined current knowledge on the use of probiotics in dogs and cats. The intestinal microbiota plays a crucial role in protecting the barrier function of the gut, supporting nutrition and metabolism, and regulating immune responses. Disruptions to this balance, known as dysbiosis, are linked to a range of diseases in both humans and companion animals.
In recent years, probiotics derived specifically from canine and feline sources have been isolated and tested. Studies consistently show that their administration can improve gut health and help manage certain intestinal disorders. While the positive effects are evident, the underlying biological mechanisms remain only partially understood.
The authors emphasize that probiotics offer a promising tool for promoting digestive health in pets. However, more targeted research is needed to identify the most effective strains, clarify mechanisms of action, and establish best practices for long-term use in pet care.
