A buyer's checklist

Before you buy a skin & coat supplement, check these five things

Glossy photos and big promises are easy. The label tells you what your dog would actually get. Here's what to look for, whichever brand you choose.

Five label checks

Take a photo of the label of anything you're considering, or already have, and go through these one by one.

  1. The amount of each active ingredient, per serving

    Ingredient names on the front aren't amounts. Look for a panel that lists each active ingredient with a number, usually in milligrams, and says what a serving is: a chew, a scoop or a number of mL. Then work out what your dog would get per day at their weight.

    Ask: How much of each active ingredient will my dog actually get per day?

  2. The serving for your dog's weight

    Most skin and coat supplements are dosed by weight, so a bigger dog may need two or three times the serving of a small one. That changes how long a container lasts and what it really costs.

    Ask: What does the label's serving chart say for my dog's weight?

  3. The cost per day, not per bottle

    Divide the price by the number of full days the container covers at your dog's serving. Two products with the same price can have very different daily costs.

    Ask: What does this cost per day for my dog?

  4. Where the ingredients come from

    Skin and coat products often use fish, bovine or poultry-derived ingredients. If your dog has food sensitivities, the source matters as much as the amount. Look for an allergen statement, or ask the company directly.

    Ask: What is each ingredient sourced from, and does it contain anything my dog shouldn't have?

  5. What the company can actually show you

    Look for a lot or batch number, a certificate of analysis you can read, a real way to contact the company, and plain claims. Be wary of promises like "stops itching" or "treats allergies". Products like these aren't approved to treat disease, and a skin problem deserves a vet's look.

    Ask: Can you share the certificate of analysis for the batch I'd receive?

If You've Tried A Few Already

It's common to try more than one skin and coat product. Without the label facts side by side, it's hard to know whether you compared like with like: different amounts, different serving charts, different daily costs.

Writing these five things down for each product turns a guess into a comparison, and gives your vet something concrete to look at.
