A recent UK study published in PLOS One analyzed the nutritional composition of 31 commercially available dog foods, including meat-based, plant-based, and veterinary options. The study found that plant-based diets for dogs can be nutritionally adequate, with the only exceptions being lower levels of iodine and B vitamins. These nutrients can easily be supplemented to ensure a balanced diet for dogs on plant-based diets.

The researchers concluded that plant-based diets for dogs can provide the necessary macro- and micronutrients for a healthy diet, similar to meat-based options. Previous studies have also shown positive health outcomes for dogs on plant-based diets, making them a viable and potentially beneficial alternative to traditional meat-based diets. Further research, including long-term feeding studies, will help continue to explore the benefits and feasibility of plant-based diets for dogs.
