Blue Buffalo Vs Science Diet
The Most critical facts you need to know! to maintain healthy muscle, immune system, bones, teeth and joints of your dog.
Your small breed senior dog is still a vital part of your family. Shouldn’t you want to feed them the best senior-focused kibble, so they maintain healthy muscle, immune system, bones, teeth and joints.
Both promise healthy hearts, muscles and minds and they are comparable in price around $30-35 for a 15-lb. bag of Science Diet® , while Blue Buffalo® goes for about $23-25 for a comparable-sized bag on the same site.
And both brands also meet the AAFCO (American Association of Feed Control) for balanced nutrition and a level of quality.
Blue Buffalo® Life Protection Formula Chicken and Brown Rice for Small Breed Senior Dogs
They follow that with a second protein source, chicken meal. Chicken meal is the “nasty parts” of the chicken – beaks, feet, stomach, livers, brains, and occasionally a fetus – that most humans would have a hard time eating. However, this processed food of chicken offal is full of vitamins, minerals and fats that your dog needs to build healthy, lean muscles; a shiny coat and easier digestion
They follow that with brown rice, an easily digestible carbohydrate. It is less processed and higher in fiber and ash, which makes it easier to digest and easy on a senior dog’s sensitive stomach.
Barley is the next ingredient in Blue Buffalo’s® Life Protection Formula. It is a good form of carbs and fiber for your dog and it is frequently found in premium dog food brands. Barley is also loaded with gluten. So, if your dog is allergic to gluten-based ingredients, Blue Buffalo might be one to pass on.
Hill’s® Science Diet® Adult 11+ Small & Toy Breed Age Defying Dog Food
Hill’s® Science Diet® Adult 11+ Small & Toy Breed food also starts with chicken, but not whole chicken. Instead they use chicken meal – you remember all those nasty chicken parts.
Many dog foods, especially premium brands, use some type of protein meal as their first ingredient. While it is also a good source of protein, meat meals are highly processed, low in moisture, have a high ash content, and lower levels of vitamins and Lysine. Most dogs can easily digest this ingredient, but it is not the same as having an actual meat as the first ingredient.
Brewer’s Rice is the second ingredient in Science Diet®. Brewer’s Rice is highly processed and often use by beer producers for flavor, hence the name Brewer’s Rice. But your dog is not eating rice used in the brewing process; this ingredient is simply small fragments of rice that separated from larger kernels of the grain. They are easy and inexpensive to add into your dog’s food.
This type of rice is an easily, digestible carbohydrate and provides fiber for your dog. However, it is empty in nutritional value and is used as a filler in your dog’s bowl. According to vets, they recommend finding a food that uses this ingredient sparingly, since it is still a carb and could cause you senior dog to gain weight unnecessarily.
Science Diet® rounds out the top five ingredients with more grains – whole grain wheat, whole grain sorghum, and cracked pearled barley. These carbohydrates are considered better for your dog since they are whole grains and contain more vitamins and minerals than processed wheat or barley meals.
Brand comparison Blue Buffalo Vs Science Diet
Blue Buffalo® also adds sweet potatoes, carrots, tomatoes, parsley, apples, spinach, blackberries, pomegranate and pumpkin to it Life Protective formula. The addition of these vegetables and fruits adds more fiber, vitamins, and flavor to the food. They also improve your dog’s immune system.
Science Diet® also contains non-traditional ingredients, including dried beet pulp, apples, broccoli, carrots, cranberries and green peas.
Finally, a food that includes a variety of vegetables in the ingredient list, can help prevent certain diseases – such as cancer or kidney disease.
Both foods contain added glucosamine or chondroitin to help your dog with joint issues. However, you would have to overfeed both brands to your dog to see any tangible results from these ingredients.
According to dogfoodproject.com, a 50-lb. dog with light to moderated joint problems would need 500 to 750 mg of glucosamine a day for noticeable changes in their joint health. However, even dog foods fortified with glucosamine or chondroitin only provide 50-100 mg per cup. To even close in on the recommended daily dose of glucosamine, you would have to feed your dog 5-10 cups of food per day! That totals almost 3,500 calories a day, which would lead to a very overweight dog.
Instead, look for these ingredients on the bag (they’re good for your dog), but if they have joint problems, ask your veterinarian for a glucosamine/chondroitin supplement.
Blue Buffalo® adds tocopherols in its chicken fat as a natural antioxidant that prevents spoilage. It helps maintain the flavor and nutrients in the dog food.
