Is Leader Arthri-Can Chews a good dog food?

Who is this food for?

Suits

Labelled by the manufacturer for all lifestages
Single named protein: fish
Doesn't list chicken, beef, turkey, lamb, venison, pork, duck as ingredients

Consider something else if:

Your dog avoids grain: the label lists maize / corn
You need more protein than this: 13.5% on a dry-matter basis is in the low band

These points are derived from declared ingredients and analysis, not a substitute for veterinary advice. If your dog has a diagnosed condition, food choice is a medical nutrition decision: speak to your vet. Use the homepage filter to find foods that fit your dog.

This is not a complete diet, so the 1-100 rating does not apply to it. Read the recipe breakdown above as ingredient-quality context only.
