Home-Cooked Vs Commercial Dog Food: What The Science Actually Says (Part 22)
The Great Debate: Home-Cooked vs Commercial Dog Food
As a responsible pet owner, you’re likely no stranger to the debate surrounding home-cooked versus commercial dog food. While some swear by their homemade recipes, others rely on their veterinarian-recommended products. But what’s behind this seemingly innocuous divide? Let’s dive into the science and explore what’s worth considering.
Nutritional Balance
Commercial dog foods are often criticized for lacking the nutritional balance of a homemade diet. Research suggests that commercially available kibble can lead to an imbalance of essential vitamins, minerals, and amino acids (1). This is because manufacturers may prioritize cost over quality, resulting in a diet that neglects the unique needs of individual breeds or life stages.
For example, a study on German Shepherds found that their commercial food contained excessive amounts of phosphorus, which can lead to kidney damage (2). Similarly, a Canadian investigation revealed that many store-bought dog foods were lacking in essential fatty acids, which are vital for maintaining skin and coat health (3).
On the other hand, homemade diets often require more attention and precision. For instance, some breed-specific recipes can be tailored to meet an individual dog’s unique nutritional needs.
Protein Quality
Commercial dog foods typically contain a mix of protein sources, such as meat by-products or soy protein concentrate. However, this may not provide the highest-quality protein options (4). Some studies have suggested that certain protein sources, like chicken and fish meal, can be more nutritious than others (5).
In contrast, homemade diets often allow for the use of high-quality protein sources, such as fresh meat and fish. For instance, a study on mixed-breed dogs found that those fed dog food containing whole muscle meat had improved kidney function compared to their commercial counterparts (6).
Taurine and Vitamin E
Commercial dog foods often contain lower levels of essential vitamins and minerals like taurine and vitamin E than homemade diets (7). Taurine is particularly important for heart health, vision, and bone growth. Vitamin E, on the other hand, helps protect against oxidative stress and supports skin health.
On the other hand, some breed-specific recipes often include high levels of these nutrients to support specific needs (8).
Actionable Tips
If you’re considering switching from commercial dog food to a homemade diet, here are a few things to keep in mind:
