Why this product is in the Depot

A senior dog’s digestive system can become more sensitive over time, and maintaining a healthy balance of gut bacteria is essential for their overall immunity. I included FortiFlora because it provides guaranteed levels of live cultures that are specifically formulated to survive the stomach’s environment and support a stable digestive tract.

How I use it

I originally used this supplement only after Maya had a procedure or was taking antibiotics, but I transitioned to daily use when she was 15. Since I found that a full 1g sachet was a bit too rich for her stomach, I now sprinkle about one-third of a packet into her food once a day. This smaller, consistent dose keeps her gut “right” without causing any digestive upset.

Why I recommend it

I recommend this because it is a trusted tool for many dog health professionals, including my dog physiotherapist, who emphasizes the link between gut health and reduced inflammation throughout the body. I’ve seen firsthand how it helps Maya maintain consistent stool quality and a settled stomach, especially when she is on other medications that might otherwise cause distress.

Considerations

  • Dosage Adjustment: While the box suggests one sachet daily, pay attention to your dog’s reaction; as I did with Maya, you may find that a partial dose is more effective for very senior dogs.

  • Palatability: The powder has a flavour that most dogs love, making it a great “topper” to encourage a senior dog with a fading appetite to finish their meal.

  • Storage: Keep the sachets in their original box in a cool, dry place to ensure the cultures stay active and effective.
