Parker is a Katrina rescue. The other puppies in his litter died and he suffered kidney problems as a young puppy. But his human has followed a holistic protocol, making him a homemade diet, giving him herbs and avoiding medications that could impact his kidneys. Today, eight years later, his renal levels are normal, better than when he was a puppy. And he has thrived because of the additional care, no arthritis, no tumors, no allergies. Here are the herbs I like to use in powder form: Foti root, Ashwaganda root, Hydrangea root, Nettle root. It helps most dogs with kidney problems and that is a growing number of dogs, perhaps due to increased immune-mediated diseases affecting the kidneys.
