Pet Allergy Supplements is an independent editorial research site about allergy, itch and immune-support supplements for dogs and cats. We read product labels, ingredient amounts and sourcing claims, compare them side by side, and check what published veterinary research actually says, so pet owners can make a better-informed choice and know when a supplement is not the answer.
Who we are
Pet Allergy Supplements is an independent editorial site. We are not a veterinary clinic, a manufacturer or a retailer, and no supplement brand owns or funds this site. Pages are researched and written by the site team and are not currently reviewed by a veterinarian. We do not publish under invented names or credentials. Our pages are research summaries, and we say where the evidence comes from so you can check it yourself.
We use software tools, including AI tools, to help with research and drafting. Every health claim, product fact and number is checked against the cited source or the product label before a page is published or updated.
What we do
- Compare labels. Active ingredients, amounts per serving, serving sizes by weight, inactive ingredients and species on the label.
- Check ingredient amounts. For example, whether a colostrum states an IgG percentage, or how much EPA and DHA a fish oil gives per serving.
- Look at sourcing claims. Country of origin, grass-fed or first-milking statements, and third-party certifications such as NASC. We report these as brand statements, not as verified facts.
- Read the research. Veterinary guidelines, veterinary manuals and peer-reviewed studies on PubMed and similar sources. We rate the evidence as strong, moderate, limited or not studied, and we note when a study was funded by a company that sells the product type.
How we choose products
A product makes it onto a page when it fits that page's topic and passes most of these checks:
- The label clearly lists the active ingredients and the amount per serving.
- The label states which species it is for, with dosing by weight.
- The ingredients match the job (for example, a single-ingredient colostrum for a food-sensitive dog rather than a multi-protein chew).
- Published evidence supports the main ingredient, even if that evidence is limited, and we say how strong it is.
- The brand gives useful information on sourcing, standardization or quality testing.
- There are no obvious red flags, such as essential oils in a cat product or claims to cure disease.
We also include a "watch-out" for every product, because no supplement suits every pet.
What we don't do
- We don't lab-test products. We have not run our own potency or purity tests, and we do not claim to have used the products ourselves. Our comparisons are based on labels, brand information and published research.
- We don't accept paid placements. Brands cannot pay to be included or ranked higher.
- We don't set prices. Prices and availability change often, so we do not list them. Check the current price on Amazon before you buy.
- We don't diagnose. We will tell you when a symptom needs a vet rather than a supplement.
Affiliate disclosure
As an Amazon Associate I earn from qualifying purchases. When you click a "Check price on Amazon" link and buy something, we may earn a commission at no extra cost to you. This is how the site is funded. Commissions do not decide which products we include or how we describe them, and we are happy to say when a supplement is not worth it or when your pet needs a vet instead. The checks a product has to pass are listed under how we choose products, and the rules we write by are in our editorial policy.
Medical disclaimer
The content on this site is for general information only and is not veterinary advice. It does not replace an exam, diagnosis or treatment from a licensed veterinarian. Supplements are not approved to treat or cure disease. Always talk to your vet before starting a supplement, especially if your pet is a puppy or kitten, pregnant or nursing, elderly, on medication, or has kidney disease, liver disease, a food-elimination trial in progress, or another medical condition. If your pet has open wounds, sudden severe itching, vomiting, diarrhea, facial swelling or trouble breathing, contact a vet right away.
Editorial policy
- Sources first. Health statements are based on veterinary guidelines (such as the ICADA atopic dermatitis guidelines), veterinary manuals, FDA labels and peer-reviewed studies. We link the source next to the claim so you can read it yourself, and we only cite what we have actually read.
- Brand claims are labeled as brand claims. Sourcing, purity testing and "made with" statements are reported as what the brand or listing says, unless an independent source confirms them.
- One evidence scale. We use the same words across the site: strong, moderate, limited or not studied. Omega-3 for itchy skin is rated moderate with a small benefit; colostrum, probiotics and quercetin are rated limited.
- No drug doses. We describe prescription options and their label warnings, but dosing a medication is your vet's job. For supplements we point to the label directions rather than writing our own dosing charts.
- Commercial independence. Affiliate commissions never decide whether a product is included or how it is rated, and we will say when the right answer is a vet visit rather than a purchase.
- Who reviews the pages. No veterinarian reviews our pages at present. If that changes, the reviewer's name and credentials will appear on the pages they reviewed. We will never invent a reviewer.
Corrections
Labels change, products are reformulated, drugs get new approvals and label warnings, and new research is published. We review our pages and update them when a label, an ingredient amount or the evidence changes. Each page shows the date it was last updated.
If you spot an error, an outdated label or a broken source link, please tell us through our contact page. Include the page address and, if you can, a link to the source that shows the correct information. We check every report against the original source. When we correct a fact, we fix the page itself and update its date; if a correction changes a recommendation or a safety statement, we say so on the page.
