Top 5 Vitamin K for Dogs in Canada (2025) — Vet-Recommended, Evidence-Based Options: Which One Is Right for Your Pet?

Published on Thursday, August 21, 2025

Vitamin K is critical for normal blood clotting and is used in veterinary care to treat or prevent coagulopathy from certain toxins or deficiencies. In Canada, products for dogs range from prescription-strength vitamin K1 tablets used under veterinary supervision to over-the-counter oral supplements formulated for maintenance or mild deficiencies. Pet owners typically choose products based on the intended use — emergency reversal of rodenticide exposure, long-term support for dogs with absorption or liver issues, or a palatable daily supplement. Consumers in Canadian urban and rural markets prioritize veterinary recommendation, clear dosing guidance, product safety, and availability (prescription versus over-the-counter). Other deciding factors include formulation (tablet, chewable bite, liquid), palatability for picky dogs, predictable strength per dose, ingredient transparency, and Canadian shipping and regulatory considerations.

Research and Evidence Behind Vitamin K Use in Dogs

Veterinary research and clinical guidelines explain why vitamin K is the standard treatment for certain bleeding disorders in dogs. Vitamin K1 (phylloquinone) is required for activation of clotting factors II, VII, IX, and X and regulatory proteins C and S. In practice, veterinary toxicology literature and consensus guidelines support oral or injectable vitamin K1 for reversal of anticoagulant rodenticide poisoning and for treating vitamin K deficiency due to malabsorption, cholestatic liver disease, or prolonged antibiotic use. Safety studies and clinical reports also guide dosing strategies and monitoring in canine patients.

Mechanism: Vitamin K1 enables gamma-carboxylation of clotting proteins needed for normal coagulation, which is why deficiency or toxin-induced antagonism leads to bleeding.

Rodenticide reversal: Multiple veterinary toxicology sources and clinical case series support use of vitamin K1 (typically oral) to reverse bleeding from warfarin-like rodenticides after decontamination and supportive care.

Dosing and onset: Oral vitamin K1 is commonly used with dosing tailored to body weight and toxin type; clinical effect can take 12 to 48 hours as new clotting factors are synthesized, so monitoring and follow-up are essential.

Safety profile: Vitamin K1 has a favorable safety profile when given at therapeutic doses; adverse reactions are uncommon but monitoring is recommended when used with other medications.

Clinical contexts: Evidence supports vitamin K supplementation in dogs with malabsorption or cholestatic disease where dietary or bile-dependent vitamin K uptake is impaired.

Guidelines and sources: Information is drawn from veterinary toxicology textbooks, peer-reviewed case reports, and consensus recommendations used by veterinarians and emergency clinics.

In Canada, the right vitamin K product depends on the situation. For prescription-strength, vet-supervised reversal of toxin-related bleeding, Vetoquinol Vitamin K1 Tablets are often the preferred clinical choice. For maintenance or supplement options, NaturVet Vitamin K Plus, Rx Vitamins Rx Vitamin K, Vet's Best Advanced Vitamin K Complex, and Zesty Paws Vitamin K Bites each offer different formats and dose profiles to suit owner preferences and dog needs. We hope you found what you were looking for — you can refine or expand your search using the site search to compare formulations, dosing, and availability across Canadian retailers.
