How to compare dog supplements

Most of this category comes down to a handful of active ingredients. Compare the milligrams of active per dose against your dog's weight rather than the price on the tub.

Joint: glucosamine, chondroitin, green-lipped mussel, undenatured type II collagen and omega-3 (EPA/DHA). Chew count and per-chew potency vary widely between brands.
Liver: SAMe and silybin (milk thistle) are the two actives used in most veterinary liver products. Check whether a product is enteric-coated and whether it is dosed once or twice daily.
Skin and coat: combined EPA and DHA content is what matters, not total fish oil volume.
Digestive: compare CFU count at end of shelf life and which strains are listed. Some products also add prebiotic fibre or kaolin.

Talk to a pharmacist before you start

Speak with us first if your dog takes a prescription NSAID, phenobarbital or potassium bromide, an ACE inhibitor, insulin, or a thyroid medication, or if your dog has known liver or kidney disease. Supplements are not a substitute for veterinary care or for a prescribed medication.

Questions about a specific product or dose? Call the pharmacy at 613-824-3111, or see how our pet prescription and compounding service works. Also browse cat supplements or the full pet supplements range.
