Particularly low grade, highly contentious or excessively vague ingredient we usually recommend avoiding
Soya in dog food
Soya beans (soya, soybean protein, soya meal) are high in protein and are often added to foods as a low-cost meat substitute. Unfortunately, the proteins in soya are much less bio-available to dogs than normal meat proteins meaning that far less can be digested and used. Soya has also been consistently linked by veterinarians to food intolerance and allergies and is therefore best avoided if your dog is very sensitive.
