Sano N - Kidney Diet

Dietary complete food for dogs to support kidney function in cases of chronic renal insufficiency

Happy Dog Sano N is used to support kidney function in cases of chronic kidney failure. The particularly tasty recipe with the protein sources egg, salmon, and cracklings promotes food intake and ensures your dog's nutrient supply. This kidney diet also features specially tailored phosphorus and sodium levels. Due to the reduced protein content, this kidney diet is particularly suitable for dogs in the advanced stages of chronic kidney failure.

Adjusted protein, phosphorus and sodium levels help relieve the strain on the kidneys

The particularly tasty ingredients promote feed intake

Vitamin E as an antioxidant binds free radicals and ensures active cell protection

Additional information: It is recommended to seek the advice of a veterinarian before using Happy Dog Sano N or before extending the feeding period and to continue to have kidney function checked regularly. 

 

For optimal results, only the diet should be fed. Supplementary feeding should be discussed with your veterinarian. Unless otherwise recommended by your veterinarian, offer your dog several small meals per day.

The amount of food should be adjusted to your dog's individual metabolism and may need to be reduced or increased moderately.

Please make sure that your dog has access to water. The recommended feeding period for Happy Dog Sano N is initially up to six months. In most cases, lifelong feeding is necessary.

Who is
Happy Dog?

For over 50 years, we've been producing premium nutrition, specialising in novel and single-protein diets for healthy skin and digestion!

Award Winning

From a small family business to Germany’s best dog food brand, Happy Dog has been perfecting premium nutrition for over 50 years—trusted by pet parents everywhere!

Premium Nutrition - no fads

Happy Dog’s Natural Life Concept® delivers premium nutrition with up to 90% animal protein, essential nutrients, and natural ingredients—keeping your dog healthy from nose to tail!

Gentle Cooking Process

Crafted in Bavaria using our Thermostufenmix® process, Happy Dog dry food preserves essential nutrients for a wholesome, balanced, and delicious meal every time!

The Meat Content Myth: What Really Matters

Ever heard less is more? In pet food, that’s often the case. The industry loves its marketing buzzwords, and meat content is just another one. Here’s the truth: meat is 75% water. So when a food claims to be 80% meat, that doesn’t mean 80% protein—once the water’s gone, the real protein content is closer to 20%.

At Happy Dog, we cut through the noise. Our dry food delivers up to 90% animal protein in total protein content, ensuring real, digestible nutrition—not just clever numbers on a label. Because what matters isn’t how much meat goes in—it’s the quality of the protein and matching how much protein your dog needs to their activity levels.

Family-Owned, Locally Sourced, Truly Transparent

At Happy Dog, we’re a family-run business, not a corporate giant like Mars or Nestlé. We produce our own food in Bavaria, sourcing high-quality ingredients from local farmers instead of white-labelling from mass manufacturers like Golden Acres. With short delivery routes for freshness, carefully selected meats, and premium regional ingredients, we ensure transparency, sustainability, and real quality in every bite—because your dog deserves the best.

Happy Dog's Paw to Paw

  • £1 = 1 Meal Token

    Every time you collect 10 Meal Tokens, it translates into a generous donation of 300 grams of nutritious Happy Dog dry dog food. This is the equivalent to the daily dietary needs of a medium-sized dog, such as a 25kg Labrador.

    What are my points 

  • At the end of every month we donate the food.

    We'll convert all redeemed Meal Tokens into dog food donations for rescue centres in the UK or ROI.

    And you, our valued customers, get to have a say where!
