Raw Feeding


For the Nerds


Defined by Science

RAW FED AND NERDY was created in response to the growing concern regarding the lack of nutritional guidelines being considered when raw feeding. Raw Fed and Nerdy is science based raw feeding. RFN is primarily a Facebook Group Community for those feeding raw and wishing to collaborate with other raw feeders utilizing specific nutritional guidelines of dogs and cats, and venture away from pop-cultural raw feeding guidelines and hardcore ratio antics. Raw feeders using nutrient guidelines face unique challenges. As a community driven group, we bring together science based sources for nutritional excellency. Raw Fed and Nerdy also provides education in cooked, homemade diets and education in commercial food selection.

All admins are enrolled in or have taken pet nutrition courses and actively work in science based raw feeding.

We are a small, motivated, community driven, and well researched group.

Savannah Welna, Cert. ACN created the group after being inspired by professionals in the field as well as recognized need for raw feeding groups based on nutrition science. She understands raw feeding has its own unique nutritional challenges (bones, for example). She wants you to know that it is through the encouragement of many others that RFN was created in the first place. Despite creating the group, she hopes you recognize the value each admin and member contributes. This is not the Savannah Welna show.

Savannah lives in Montana with her husband Luke and her dog Luca. She does animal rescue for Wigglin’ Home Boxer Rescue and has done animal rescue work for 5 years.

Savannah also works independently at Feed Thy Dog where she works with proactive and therapeutic cases (sick and healthy dogs), using raw and cooked diets,  and provides in-depth recipe analysis. She also provides feedback for those feeding their dog a homemade diet.

Savannah shows her care for companion animal health by providing free assistance and ongoing support in the Raw Fed & Nerdy, free of charge, ALWAYS. To sign up for a one on one Q and A session,  you can email her at savannah@feedthydog.com with your request.
