Dogs with reduced kidney function (renal insufficiency) require special food with reduced phosphorus and protein content. A typical symptom of kidney problems is the reduced ability to dissolve phosphorus. Additionally, the kidney's ability to dissolve specific end products of protein metabolism is also reduced. High protein content can thus limit kidney function. The proteins provided in INTEGRA® PROTECT are particularly high quality to fully meet the protein needs of dogs despite the reduced content. Furthermore, limited kidney activity means that a slight increase in vitamin D3 content in INTEGRA® PROTECT Nieren is required. High acceptance and easy digestibility are distinguishing features of this product. To ensure optimal food supply, offer your dog the daily food amount divided into 3 different meals if possible. Especially in cases of chronic renal insufficiency, it is important to give this diet exclusively throughout the dog's life. Adding “normal” feed products, meal leftovers, and other complementary foods should be avoided to prevent compromising treatment success.
