Forthglade Grain-Free Dog Food
Forthglade's grain-free range replaces cereal with vegetables and other carbohydrate sources alongside a named meat, and it's sold as ready-to-serve wet trays rather than a bag of kibble. We carry a selection of the grain-free line, and it's worth knowing what actually changes compared with their standard recipes before picking one.
What grain-free means in this range
Forthglade's grain-free recipes swap out cereals like wheat or rice for ingredients such as sweet potato or other vegetables, while keeping a named single meat as the main protein source, the same approach the brand uses across its wider range.
It's a natural, minimally processed wet food rather than a dry kibble, so texture and preparation are quite different from a grain-free dry food even though the ‘grain-free’ label means the same thing on the ingredients list.
Who tends to choose grain-free
Owners managing a known grain sensitivity, or simply preferring to avoid cereal in their dog's diet, are the main reason grain-free ranges like this one get picked over a standard recipe. It isn't a requirement for most dogs, who digest grain without any issue.
If your dog hasn't had a problem with grain before, there's no particular need to switch, though plenty of owners choose the range simply for the recipe or protein on offer rather than the grain-free label itself.
What to check before switching
As with any change of food, introduce a Forthglade tray gradually alongside whatever your dog currently eats rather than swapping everything over in one go, giving their digestion a few days to adjust.
If your dog has a known sensitivity to a specific protein rather than grain itself, check the named meat in each recipe carefully, since grain-free doesn't automatically mean free of whatever ingredient is actually causing the problem.

Common questions
- Is Forthglade's grain-free range suitable for puppies?
- Forthglade makes both puppy and adult recipes, so check the specific pack for the correct life stage rather than assuming any grain-free tray suits a growing puppy.
- Is grain-free food better for a dog's digestion?
- Not automatically; most dogs digest grain perfectly well, and grain-free only makes a real difference for a dog with a specific known sensitivity to cereal. It's a choice rather than a general upgrade.
- Can I mix Forthglade grain-free trays with dry kibble?
- Yes, plenty of owners feed a wet tray alongside a dry food, and most dogs manage a mixed diet without issue. Introduce any change gradually if your dog hasn't had this food before.
- Does Forthglade grain-free need refrigerating?
- Once opened, any leftover portion should be kept in the fridge and used within the time shown on the pack, the same as any wet or fresh dog food.
