Backed By Science
Our health-first approach to feeding dogs more plant-rich pet diet is backed by science. Click the studies to learn how dogs thrive on vegan diets.
What is most important when pet owners choose pet food? Studies show that fresh, human-grade ingredients with minimal processing is key.
“Dogs have nutrient requirements, not ingredient requirements.”
Nutritionally sound vegan diets are the healthiest choice
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.
The genetic difference between dogs and wolves supports adding more veggies to your pet's diet
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.
" The pooled evidence to date indicates that the healthiest and least hazardous dietary choices for dogs are nutritionally sound vegan diets."
A key feature in the evolutionary transition from wolf to domesticated dog was a change in diet
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.
Vegetarian Diets vs. Meat-Based Diets
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.
Dogs fed a meat-free diet showed no physiological difference to dogs fed animal protein
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.
" Rates of degenerative diseases such as obesity, cancer, heart and kidney disease are rising in dogs to unnatural levels and long-term exposure to unhealthy diets is the most common preventable cause."
Fresh, human-grade food found to be more digestible than processed kibble
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,.
Gently Cooked Pet Food vs. Kibble
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.
The extent of processing done to dog food makes a big difference in your dog's diet
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.
