Darleen Rudnick is a Certified Holistic Nutrition Practitioner with a Master of Science in Holistic Nutrition and a Bachelor's Degree in Social Work. She has helped pet owners improve the health and quality of life of their dogs and cats through personalized nutrition and lifestyle recommendations.

“I have been studying pet nutrition since 1986. As founder of Purely Pets, one of the early pioneers in online pet health and nutrition, I built a business that served thousands of pet owners nationwide. After selling the company, I devoted my full attention to providing individualized nutrition consultations for pets facing both common and complex health challenges.
My areas of expertise include nutritional support for pets with seizure disorders, allergies, digestive disorders, cancer support, kidney disease, diabetes, skin conditions, senior pet wellness, and Feline Hyperesthesia Syndrome. I have worked with rescue organizations, spoken at educational workshops, and advised pet owners around the world.
I have contributed to 'Canine Epilepsy: An Owner's Guide to Living With and Without Seizures,' authored 'Home Cooking for Sick Dogs,' and published multiple articles in the Virginia-Maryland-Washington DC Dog Magazine.
Today, every consultation is personal. Every pet has a unique story. I continue this work because I care about helping pet owners make informed decisions that support the health, comfort, and happiness of the animals they love.”
