Purina Pro Plan FortiFlora is the number one veterinarian-recommended probiotic supplement for dogs, formulated with the live active culture Enterococcus faecium SF68 that has been clinically proven to promote intestinal microflora balance and support a healthy gut. Veterinarians commonly recommend FortiFlora for dogs with diarrhea, digestive upset from dietary changes, stress-related GI issues, and antibiotic-associated digestive disruption. The pre-measured single-serve sachets ensure consistent dosing and mix easily into food. An interesting secondary benefit is that many dogs find the supplement extremely palatable, making it an effective appetite stimulant for picky eaters who otherwise refuse meals. The 30-sachet pack provides a full month of daily supplementation. For dogs prone to digestive issues, those on antibiotics, or picky eaters who need meal encouragement, FortiFlora is one of the most veterinarian-endorsed pet supplements available.
