Simpsons grain-free dog food: which recipes qualify
Simpsons makes both grain-free and grain-inclusive dog food, so "Simpsons grain-free" describes one part of the wider range rather than the whole brand. The Sensitive line and the 80/20 recipes are potato-based with no cereals at all; the Rice range genuinely is not.
The two halves of the Simpsons range
Simpsons' Sensitive recipes — built around a single named protein such as duck, salmon, lamb or chicken, paired with potato — list no cereal ingredient. The 80/20 recipes, which lead with a high percentage of named meat or fish, are built the same way, with potato rather than rice, maize or oats providing the carbohydrate.
Separately, Simpsons also makes recipes such as Chicken & Rice and Senior Light Chicken & Brown Rice, which do include brown rice, maize and oats in the ingredients list. These aren't a lesser product — they're simply built to a different specification, and the two exist side by side in the same brand.
How to tell the two apart when you're ordering
The clearest signal is the name: recipes described as "Sensitive" or "80/20" are the grain-free side of the range, while anything naming rice, or described as a "Rice" recipe, contains cereals. Where you're not sure, the composition panel on each product page settles it — potato listed early with no cereal named means grain-free; rice, maize or oats anywhere in the list means it isn't.
Neither side of the range is inherently better for every dog. A dog with a known grain sensitivity may do better on the potato-based recipes; a dog with no such issue can do perfectly well on either.

Common questions
- Is Simpsons a grain-free brand?
- Partly. The Sensitive and 80/20 recipes are grain-free, built around potato rather than cereals, while other recipes in the range, such as the Rice line, do contain grains like rice, maize and oats. Check the specific recipe rather than assuming the whole brand is one way.
- Which Simpsons recipes are grain-free?
- The Sensitive recipes (Duck & Potato, Salmon & Potato, Lamb & Potato and Chicken & Potato) and the 80/20 range are grain-free, using potato as the main carbohydrate rather than any cereal.
- Does my dog need a grain-free food?
- Only some dogs genuinely benefit from avoiding grain, usually those with a diagnosed sensitivity. Most dogs digest cereals without any issue, so it isn't a default requirement — check with your vet if you suspect a specific sensitivity.
- Can I switch between the two ranges?
- Yes, but introduce any change gradually over several days by mixing increasing amounts of the new food with the old, rather than swapping in one go, to give your dog's digestion time to adjust.
