The product’s natural ingredient list aligns with the goal of providing a gentle, herbal approach rather than traditional antibiotics, which can be harsh on dogs. The inclusion of antioxidants and immune-supporting herbs adds extra benefits beyond urinary care. While it supports urinary health, this supplement is not a direct antibiotic and should not replace veterinary treatment for active infections. Also, as with any natural supplement, individual dogs may respond differently, so close monitoring and consulting a vet are important. The dosage is straightforward, but owners should follow guidelines based on their dog's size and needs.
