History

Let's take a deeper dive into how these companies were founded and what missions and goals they pursue. A brand's history is an important part of selecting the best pet food for your buddy.

Science Diet

Hills was created by veterinarian Dr. Mark Morris. After seeing the link between poor nutrition and pet diseases, Dr. Mark Morris developed a pet food that was superior to any other on the market. Soon, Dr. Morris met a blind man, Morris Frank and his beloved guide dog Buddy. Buddy was suffering from kidney disease. Dr. Morris knew that many commercial pet foods available at the time contained large amounts of phosphorus and protein to improve their taste, and that their consumption could damage the kidneys. So he set about developing special diet to support kidney function. This is how Hill's Prescription Diet k/d was created, which became the first commercially available Hills pet food. This allowed Morris and Buddy to spend many more happy years together.

Dr. Morris's son Dr. Mark Morris Jr. went on to help further develop Hill's Pet Nutrition over the next few decades. In 1968, the Hill's Science Diet line was provided by veterinarians and pet specialists. The line has continued to expand, and today it includes more than 50 pet foods designed for different ages and the unique needs of different pets.

Blue Buffalo

Blue Buffalo is a relatively new company that was founded in Wilton, Connecticut, in 2003.  Jackie and Bill Bishop created the company after their beloved dog named Blue lost his battle with cancer.  Together with a leading veterinarian and nutritionist, the family decided to develop a nutritious dog food that can be used for pets with health problems. The brand's slogan, "Love them like family, feed them like family" is still at the company's heart.

The food created by the Bishops was of such high quality that it quickly gained popularity with other dog owners. In less than twenty years, the brand has gone from founding to becoming a leading brand of natural pet food. In the production of these foods, natural ingredients are used, such as real meat. The founders believe that a healthy, balanced diet is the key to solving and alleviating serious health problems in pets. The company uses high-quality ingredients without animal by-products norcheap fillers.

Food Ingredients

A healthy, balanced diet is a fundamental component of your pet's life. Nutritionally balanced foods are essential while excluding anything toxic to pets. Even though our canine companions are carnivorous, they also need plants within their diet.

The necessary nutrients for the normal functioning of the dog:

• Proteins
• Fats
• Carbohydrates
• Mineral substances
• Vitamins
• Water

The protein added to the feed can be of both animal and vegetable origin, animal protein tends to be considered higher quality since they are complete proteins (containing all amino acids required). The most commonly used animal proteins are beef, chicken, eggs, fish, and by-products such as organ meats and bone meal. Parts of slaughtered poultry containing bones, head, legs, and offal are used as poultry by-products. As a source of vegetable protein, the most commonly used are corn, soy, wheat and barley products. When it comes to the protein content in your pet's diet, don't just look at the percentage, but also its quality and, consequently, digestibility.

Carbohydrates can be either digestible or indigestible. The main sources of digestible carbohydrates in many pet foods are rice, wheat, oats, barley, carrots, flaxseed, peas, and potatoes.

Dietary fiber is essential for the normal functioning of the digestive tract. Fiber is an indigestible form of carbohyrdate and sources include grain brans (oat, barley or wheat), soy hulls and beet pulp.

Fats are included as both an energy source to food and also for flavor enhancement. Pet's need essential fatty acids in their diets that they can't produce themselves. These tend to be sourced from animal fats as they are readily absorbed.

Like all mammals, dogs require vitamins and minerals to maintain their long-term health. In addition, antioxidants and preservatives are also added to commercial diets to ensure product freshness and shelf-life. Antioxidants can be of both artificial and natural origin (e.g. vitamin E).^[2]

Guaranteed Analysis

According to the AAFCO (Association of American Feed Control Officials) , each pet food package must have labels with a guaranteed analysis of the nutrient content. In each recipe, the minimum content of raw protein and raw fat should be noted, as well as the maximum content of raw fiber and moisture.

Here, we compare the most important nutrients that our pets need.

Protein is important in a balanced dog diet, as it is an integral part of building and repairing muscles and other body tissues. It helps to form new skin cells, grow hair, build muscle, and helps in the creation of hormones and enzymes needed for daily life. Protein deficiency can lead to health problems such as skin diseases, hormonal imbalances, growth retardation, and even behavioral changes. The minimum protein intake for an adult dog is approximately 18%.

Dogs require an appropriate fat composition as part of a balanced diet. Fat provides energy, taste, aroma, and most importantly, promote the absorption of certain vitamins. Common fats used in dog food include chicken or pork fat, fish oil, and sunflower oil, . The average adult dog needs a minimum of 5% fat in their diet to stay healthy.

Dietary fiber is mainly the carbohydrate residues of plant cells after digestion. There's no minimum requirement for the fiber content of dog foods. Soluble fiber absorbs water from outside the colon into the dog's bowel movements and thus helps prevent constipation by promoting regular bowel movements. Fiber is the "stabilizer" of the stool. Fiber is also great for dogs who need to lose weight, by reducing the calorie content of their food while promoting the feeling of "fullness". ^[3]

Science Diet (average)

Science Diet	Dry Dog Food	Wet/Canned Dog Food
Crude Protein	24.5%	25.8%
Crude Fat	14.8%	17.1%
Crude Fiber	4.3%	3.3%

Blue Buffalo (average)

Science Diet	Dry Dog Food	Wet/Canned Dog Food
Crude Protein	28.5%	40.3%
Crude Fat	15.0%	25.0%
Crude Fiber	7.1%	7.6%

The table shows that Hill's Science Diet provides less protein than Blue Buffalo. The difference in protein content is roughly 5-6%. In addition, Blue Buffalo wet dog foods also provide more protein than Hill's Science Diet wet foods (40% vs 25%). Like protein, fats are an essential part of a dog's body. Fats are needed for the normal physiological functions within the canine body. Hill's Science Diet and Blue Buffalo guarantee a similar amount of crude fat in their dry foods. For wet dog foods, Blue Buffalo provides significantly more fat (about 8.67% more). Blue Buffalo also typically guarantees 2.60% more fiber.
