Bramble is scientifically proven to be be healthier for dogs.

What is most important when pet owners choose pet food? Research shows that fresh, human-grade ingredients with minimal processing is key.
Bramble's feeding trial was the first ever to test a vegan dog food's digestibility against a leading meat-based pet food. The digestibility of Bramble's protein was just as high as the animal protein, and Bramble's fat absorption was even higher. Importantly, dogs fed Bramble had lower cholesterol and improved gut health.
In the largest peer-reviewed study to date, the dietary health benefits versus health problems of over 2,500 dogs were observed for one year. Vegan dogs were found to be the healthiest, showing fewer health problems, and requiring less medication and trips to the vet.
Unlike their carnivore wolf ancestors, science reveals that dogs are omnivores. In 2013, a study compared the dog genome to the wolf genome, and found a key genetic distinction between dogs and wolves is that dogs have evolved to be able to digest starches.
In 2014, another study further revealed the dog copy number of the gene, AMY2B, which allows for the digestion of starchy foods, is 5 times higher than the copy number in wolves.
Do dogs do well on meat-free diets? Yes! Upon reviewing four studies, Dr. Andrew Knight concluded that omnivorous dogs can thrive on complete and balanced vegan diets, formulated to meet all their nutritional needs, and experience a range of health benefits.
In a 2009 study, 12 sprint-racing Siberian Huskies were fed either a commercial meat-based diet for active dogs or a meat-free diet formulated to the same nutrient specifications. All the dogs remained in excellent physical condition with normal bloodwork throughout.
A recent study published in January 2021 by Dr. Kelly Swanson, a member of Bramble’s Board of Health and Science Advisors, confirmed the health benefits of feeding fresh, human-grade food. The key findings revealed that fresh, human-grade food is more digestible than even a premium animal protein kibble, which is highly processed,.
A 2018 study revealed that mildly cooked and raw meat pet diets resulted in greater digestibility (and absorption of essential nutrients) and lower blood triglyceride concentrations compared to extruded (kibble) diets.
A 2019 study revealed the considerable variability of essential nutrient digestibility among the same animal product ingredient undergoing different processing conditions (i.e., chicken meal byproducts vs. lightly processed chicken vs. steamed chicken). In sum, the most highly processed chicken meal byproduct had the lowest nutritional digestibility, whereas the least processed steamed chicken had the highest digestibility amino acid score.
