Some studies are showing that by reducing the amount of food you give your growing large breed puppy by 20% the risk of them developing joint problems such as, Hip Dysplasia is lowered by as much as 50%. Genetics may not play as big a part in reducing this issue in dogs as previously thought. Environment and food may play a bigger factor. When you think about feeding your dog, look at the quality of food you feed. After that, realize that by feeding your dog 20% less food, you could even go to a better food for your dog because he is eating less. And praise your dog after feeding if you are cutting back. The dog is aware he’s getting less and reassuring him he is a good dog, will help him make the transition to getting less to eat. A good quality food will give your dog the proper nutrition which will in turn give the dog a sense of satisfaction when digested.
