Top 8 Vitamins & Multivitamin Supplements for Dogs in Canada (2026): A Vet-Informed Guide to Targeted Nutrition, Joint and Immune Support

PetHonesty 10-in-1 Multivitamin stands out for an expansive ingredient list that typically bundles vitamins with probiotics, omegas and joint support into a single daily chew, offering technical breadth that suits owners wanting an all‑in‑one approach. Compared to peers here, it often commands a slightly higher price but delivers greater ingredient density and perceived value per chew, making it a strong choice for owners seeking multi‑benefit coverage without buying multiple specialty supplements.

PetHonesty 10-in-1 Multivitamin for Puppies positions itself as a comprehensive, technically dense option by combining vitamins with probiotics and greens to offer broader coverage in a single product, which can deliver high perceived value despite a higher cost-per-serving. Compared to simpler, cheaper brands like NaturVet or Nutri-Vet, PetHonesty is geared toward owners who prefer an all-in-one approach to maximize nutritional coverage during critical puppy development.

NaturVet VitaPet Senior Daily Vitamins stands out as a market leader for value-conscious owners, delivering essential vitamins and minerals in an accessible tablet at a lower price point than many specialty brands. While it is less feature-rich than Zesty Paws or VetriScience in terms of targeted joint or cognitive actives, its broad retail availability and consistent dosing make it a practical, budget-friendly choice for everyday senior support.

Nutri-Vet Fish Oil Softgels provide measured, easy-to-administer doses of omega-3s, appealing to owners who prioritize dosing accuracy and shelf stability for consistent skin and coat support. Technically simpler than multi-nutrient chews but more convenient than liquids, they usually deliver a competitive price point for routine supplementation without the taste issues of straight oils.

Thorne Vet Canine Basic Nutrients is a veterinary-grade supplement formulated for clinicians and pet owners who need precise, research-backed nutrient levels and high purity, prioritizing measured immune and antioxidant support over palatability. Technically superior in raw ingredient testing and potency compared with consumer chewables, Thorne Vet is usually the most expensive option but offers the strongest quality assurance and dosing control for dogs with specific health needs.

Under the Weather Ready Cal positions itself as a versatile midrange solution by combining moderate calories with electrolyte support, making it well-suited for dogs that need both energy and rehydration without the expense of a high-calorie liquid product. Financially and technically it bridges the gap between concentrated salts like Pet-ORS and premium liquids like PetAg Dyne: more caloric and palatable than straight ORS powders, yet generally less costly and easier to store than ready-to-use high-calorie syrups.

PetAg Esbilac 2nd Step Puppy Weaning Food is included as the lead feeding product for lactation scenarios because it provides a nutritionally balanced transition food for pups when maternal milk is insufficient or supplementation is needed, complementing maternal prenatal supplements rather than replacing them. Its technical advantage over vitamin-only products is that it directly supplies calories and macronutrients for growing puppies; financially, it is more of a consumable feeding cost compared with one-time supplement purchases but is essential in mixed litters or orphaned-puppy care.

NOW Pets C-500 delivers a well-known, value-oriented 500 mg dose per tablet from a mainstream supplement manufacturer, balancing quality testing and affordability for routine use. It often represents the best compromise between cost and standardized manufacturing compared with premium Ester-C or vet-grade powders, although it typically uses standard ascorbic acid rather than buffered or esterified forms favored for sensitive dogs.
