This is my go-to. It's in the dog's food every week. It alleviates any issues.. A couple years ago, my younger dog who was a plot hound yellow lab mix was having issues with readings in his urine. That weren't right and rather than take pharmaceuticals, I'd rather do this approach. So when I make their food every week, Cran Tri-C is one of the wonderful supplements that nature's farmacy makes that I am confident in because of the ingredients and I don't have to put medications in my dogs which makes them live longer and happier lives.!!
