Food tool

What is actually in your Bull Terrier's food?

Paste the ingredients list from the bag or tin. This names the common allergens it contains, the wording that will make an elimination diet impossible, and the things worth having. Nothing is sent anywhere; the check runs entirely in your browser.

Copy it off the bag, tin or the manufacturer's website. Include the additives line if there is one.

This is not veterinary advice and it is not a diagnosis. It reads an ingredients list and explains what the words on it mean. It cannot examine your dog, it cannot tell you what your dog is allergic to, and only a properly run elimination diet supervised by your vet can do that. Use this as a directional tool to help you ask better questions, and take any skin, gut or behaviour change to a qualified vet.

Quick answer
  • Beef (34%), dairy (17%) and chicken (15%) account for most confirmed canine food allergies.
  • Paste the ingredients list and the check names what is in it, including the wording that would make an elimination diet impossible.
  • Nothing leaves your browser. There is no upload, no account and no record kept.
  • It cannot tell you what your dog is allergic to. Only an elimination diet run with your vet can do that.
  • Vague labels are the real obstacle. You cannot exclude an ingredient the packaging refuses to name.

Why the label matters more than the marketing

Almost every claim on the front of a bag is undefined. "Hypoallergenic" has no legal meaning on pet food. Neither does "natural", or "premium". A food described as "with lamb" is required to contain 4% lamb, and the rest can be the chicken or beef you were trying to avoid.

The ingredients panel on the back is the part that is regulated, and it is the only part worth reading. What this check does is translate it: which of the common allergens are present, which phrases are deliberately non-specific, and which ingredients are actually worth having.

What the check looks for

  • The ten most common food allergens, with how often each one is confirmed as the trigger.
  • Vague wording such as "meat and animal derivatives", "cereals" and unnamed "flavourings", which make an elimination diet impossible to run properly.
  • Additives worth knowing by name, including BHA, BHT, ethoxyquin and artificial colours.
  • Things worth having: named omega-3 sources, well-absorbed zinc, hydrolysed or novel proteins, and prebiotics.

Frequently asked questions

What are the most common food allergens for dogs?

Across 297 dogs with confirmed adverse food reactions, beef accounted for 34% of cases, dairy 17%, chicken 15%, lamb 14.5%, wheat 13%, soy 6%, and maize and egg around 4% each. The pattern reflects exposure rather than anything sinister about those ingredients: dogs become sensitised to what they eat most, and those are the proteins in most mainstream food.

Can this tool tell me what my Bull Terrier is allergic to?

No, and nothing that reads a label can. It tells you which known allergens are present in a specific food, which is the information you need before you can run an elimination diet. Identifying the actual trigger takes 8 to 12 weeks on a single novel or hydrolysed protein, followed by deliberate reintroduction, and it should be done with your vet.

Is grain-free food better for a Bull Terrier?

Not on its own. Grain accounts for a minority of confirmed food allergies, and most grain-free foods swap grain for peas, lentils or potato while keeping the same beef or chicken protein that was more likely the problem. Grain-free is a marketing category, not a medical one.

Why does the tool flag "meat and animal derivatives"?

Because it can legally mean any mammal or bird, and the mix can change between production batches. You cannot keep a dog off beef using a food that will not tell you whether it contains beef. During an elimination trial, every protein in the food has to be named.

Does this send my data anywhere?

No. The check runs entirely in your browser and nothing you paste leaves your device. There is no account, no upload and no record kept.

Prevalence figures are from Mueller RS, Olivry T, Prelaud P, Critically appraised topic on adverse food reactions of companion animals (2): common food allergen sources in dogs and cats. BMC Veterinary Research. 2016;12:9. That review pooled 297 dogs with confirmed adverse food reactions, which is why the percentages here describe confirmed cases rather than suspicion.

Find out what is actually causing it

An ingredients list tells you what is in the bowl. It cannot tell you what your dog is reacting to, and that only comes out of a pattern: what he ate, what his skin did, and when. Log it as it happens and take real data to your vet rather than a recollection.
