Performance notes
The organic berry and apple blend is a whole-food source of polyphenols and antioxidants, which is the basis for its urinary tract support claim, rather than a single isolated compound. Since it's a powder meant to be mixed into food, palatability will depend on how well your dog takes to the apple flavor blended with its regular meal.
What buyers say
With 201 reviews averaging 4.4 stars and about 100 bought last month, Red Rover has a smaller but positive following, consistent with a more specialty, whole-food style supplement rather than a mass-market chew.
It's a powder meant to be mixed into your dog's food rather than given as a standalone chew or tablet, with each container providing 30 large dog servings.
Is this a treatment for urinary tract infections?
No, this is formulated to support urinary tract health with polyphenols and antioxidants from organic berries and apple, not to treat a diagnosed infection or condition. See a vet for any signs of a urinary tract problem.
What size dog is this meant for?
The label specifies large dog servings, so owners of smaller breeds should check with their vet about adjusting the amount.
