Only part of the analytical constituents are declared, so the nutritional picture is incomplete.

- Your dog avoids chicken: it is listed as an ingredient
- Your dog avoids turkey: it is listed as an ingredient
- Your dog avoids fish: the label lists dehydrated fish proteins
- You want a single-protein recipe: this one lists more than one animal protein
- You are limiting fat: 79.9% on a dry-matter basis is in the high band
- You need more protein than this: 7.6% 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.
