Houndztooth was founded in 2018 by Rachael Tricarico, driven by a lifelong passion for animal health, wellbeing and nutrition.
Growing up surrounded by animals on Australian farmland, Rachael developed a deep understanding of the connection between nutrition, health and overall wellbeing from an early age.
Her experience as an equestrian rider and in preparing horses for showing and dressage competitions further strengthened her knowledge of animal care, supplementation, grooming and performance health.
After studying Business and International Trade at Monash University, Rachael continued her education through the College of Integrative Veterinary Therapies, specialising in Natural Animal Nutrition.
The inspiration behind Houndztooth came from Rachael’s own dogs and her desire to create natural, effective products that genuinely supported long-term health. Unable to find products that aligned with her philosophy of functional nutrition, natural ingredients and whole-body wellness, she set out to create her own.
Today, Houndztooth proudly creates natural supplements, freeze-dried raw meal toppers, whole-food treats and grooming products designed to support dogs from the inside out using premium Australian ingredients and nutritional science.
Because when dogs feel better, they live better.

For Rachael, Houndztooth has always been deeply personal.
Her passion for animal wellbeing began long before launching the brand — from growing up with animals to years spent working within Australia’s pet industry and caring for performance horses. Through her own experiences with dogs experiencing skin sensitivities, digestive issues and anxiety, Rachael became increasingly passionate about the role natural nutrition can play in supporting long-term health.
What began as a search for better solutions for her own dogs evolved into Houndztooth — a brand built on the belief that pets deserve the same quality ingredients, care and wellness support as we do.
Today, Rachael continues to lead Houndztooth with a focus on natural ingredients, functional nutrition and creating products that genuinely help dogs live healthier, happier lives.
