Clean-tested supplements, with the paperwork to prove it
Four Leaf Rover is an American natural supplement brand founded by Dana Scott after losing two of her dogs to toxic chemical sprays used in fields near her home. Searching for safer alternatives, Dana found that almost every natural remedy on the market contained hidden or compromised ingredients. Four Leaf Rover was built in response — to give every dog access to supplements made from clean, tested, transparent ingredients.
What sets the brand apart on our shelf is the rigour behind each batch. Every Four Leaf Rover product is third-party tested for pesticides, heavy metals, and microbial contaminants, and every product comes with a Certificate of Analysis. The brand holds the NASC Quality Seal — the benchmark for quality control in the pet supplement industry — and is certified Plastic Negative by rePurpose Global, removing twice the plastic from the environment that it creates.
Ingredients are sourced from trusted suppliers across New Zealand, North America, and Europe. Organic is chosen wherever possible; non-organic ingredients are tested to confirm they are free from pesticides and heavy metals. Manufacturing is GMP-compliant. Formulas are developed in collaboration with Dr. Patricia Jordan and other leading holistic veterinarians.

Are Four Leaf Rover supplements safe for dogs of all ages?
Most products are suitable for dogs of all life stages. For puppies and very small dogs, starting at a reduced dose is recommended. A small number of products — including those containing specific herbs — may not be appropriate for pregnant or lactating dogs. Check individual product pages for specific cautions.
Can Four Leaf Rover supplements be used alongside prescription medications?
Many can, but some herbs interact with medications — particularly those affecting blood clotting, liver metabolism, or thyroid function. Always inform your veterinarian of all supplements your dog is receiving, especially before or after surgery or while on long-term medication.
Are the products tested for safety?
Yes. Every Four Leaf Rover product is third-party tested for pesticides, heavy metals, and contaminants, and comes with a Certificate of Analysis. The brand holds the NASC Quality Seal, which requires compliance with independent auditing and rigorous quality control standards.
What is the difference between Yeast Guard and Yeast Guard Plus?
Both target yeast overgrowth using antifungal botanicals. Yeast Guard is the standard formula suited to ongoing yeast management. Yeast Guard Plus adds additional antifungal and detox support, making it more appropriate for dogs with stubborn or recurring yeast issues — particularly those also dealing with skin, ear, or paw symptoms.
What is the difference between Gut Guard and Protect Soil Based Probiotics?
Gut Guard focuses on soothing and repairing the gut lining using herbs like marshmallow root, slippery elm, and licorice root — best for dogs with active digestive irritation, leaky gut, or IBD. Protect Soil Based Probiotics focuses on repopulating the gut microbiome using hardy soil-based probiotic strains alongside detox support from chlorella and bentonite clay — better suited to dogs needing ongoing gut balance and environmental toxin clearance.
Which mushroom product should I choose?
Turkey Tail is the most researched for immune modulation and gut microbiome support. Lion's Mane is more targeted at cognitive function, nerve health, and the gut-brain connection. Seven 'Shrooms combines both alongside five other organic mushrooms for the broadest immune and adaptogenic coverage. If you're unsure which to start with, Seven 'Shrooms offers the most complete foundation.
Why is Safe-Sea better than standard fish oil?
Standard fish oil provides only EPA and DHA. Safe-Sea uses green-lipped mussel oil, which contains over 30 fatty acids including ETA — a rare anti-inflammatory omega-3 not found in fish oil — alongside ahiflower oil for GLA and SDA, and astaxanthin as a potent antioxidant. Green-lipped mussel is also sustainably farmed in New Zealand, making it a cleaner and more environmentally responsible choice than wild-caught fish.
What is the difference between BiFido for Fido and Saccharomyces Boulardii?
BiFido for Fido is a bacterial probiotic — a daily multi-strain blend with Bifidobacterium species suited to dogs, best for ongoing gut microbiome support. Saccharomyces Boulardii is a probiotic yeast, not a bacteria, which makes it uniquely effective during or after antibiotic courses since it is not destroyed by them. It is typically used short-term to restore gut balance after digestive disruption rather than as a daily supplement.
Do I need a Certificate of Analysis, and how do I get one?
You don't need one to use the products — every batch is independently tested before release. But if you would like to see the COA for a specific product batch, contact us at Woof Living or Four Leaf Rover directly with the batch number printed on the container, and a copy can be provided.
