 Obesity is a growing problem in dogs, and there is an increased demand for foods rich in fibres to help reduce calorie intake and slow down digestion. Soy hulls are a low cost and readily available fibre source, and we conducted a study to evaluate the effectiveness of feeding them to adult dogs with varying degrees of body condition. The results showed that the dogs fed the soy hulls diet experienced no significant changes in body weight, body condition score, subcutaneous fat thickness, or body mass index compared to those fed a controlled diet. However, further research is needed to determine whether this type of diet would be effective for overweight or obese dogs. This article was authored by Tabata T.
