About Blue Buffalo

Blue Buffalo had its start in 2003 and was founded by Jackie and Bill Bishop. They wanted to develop healthy dog food with high-quality ingredients after their own dog, Blue, passed away from cancer. Many of Blue Buffalo’s early recipes were made for researching links between cancer and diet and nutrition.

Today, Blue Buffalo has several different lines of dog food and produces recipes for all life stages and special diets. You can find both dry and wet dog food with formulas that help with common health concerns, such as food allergies and weight management. Blue Buffalo also has a veterinary diet line that offers prescription food for dogs with more acute conditions and chronic illnesses.

While you won’t find as much variety as Purina Pro Plan, Blue Buffalo excels in selling recipes that are easily digestible for dogs with sensitive stomachs. It’s also known to be a popular choice for picky eaters.

Blue Buffalo is marketed as premium dog food and is more expensive than many other dog food brands. For the price you pay, you’re ensured to feed your dog recipes that are free of artificial flavors or preservatives. You also won’t find any soy, wheat, or corn additives.

While Blue Buffalo has a reputation for providing holistic dog food made with natural ingredients, accusations of false advertising and lawsuits have shaken up the brand’s credibility. One significant issue is the discovery of animal by-products in some of its recipes.

Blue Buffalo also has a good number of recipes that are grain-free and high-protein. While these diets may seem more palatable to dogs, research shows that there may be links between grain-free diets and heart disease. So, it’s important to do your research before selecting new dog food.
