What is the difference when an animal has an intolerance compared to an allergic reaction?
Typically, when symptoms such as scratching, skin redness, or digestive problems appear, an intolerance or allergy to something (food or an environmental substance – dust mites, pollen, grass, etc.) is suspected.
Blood tests measure IgE and IgG antibodies, and their levels.
Dog Allergies – Intolerance – Differences
These two values play different roles in the body’s immune response:
01
IgE – Immediate Allergic Reaction
An elevated level means a positive allergy test, with a reaction time of immediate (minutes to hours)
Common symptoms include itching, rash, ear scratching, paw biting, relentless licking, sneezing, diarrhea, or even anaphylaxis.
02
IgG – High Sensitivity, Delayed Manifestation
A positive test indicates high sensitivity, not necessarily an allergy, with a delayed reaction time (hours, days, weeks) or no reaction.
It can be elevated in chronic problems such as gastrointestinal issues, skin problems, or behavioral changes, nervousness.
Also, a positive IgG result often reflects past exposure, not necessarily an active allergy.
Dogs with high IgG to certain foods may tolerate that food without symptoms.
Important!
This is not a substitute for veterinary advice but an article intended to educate dog owners about the difference. Strictly restricting food for which there is a slightly elevated intolerance result is not a solution – which is why problems persist.
It is not always necessarily an intolerance problem if the result is not significantly above the upper limit. This can lead us to incorrect conclusions, preventing us from seeking further causes.
On the other hand, a positive allergy test is something that should be considered from the start and eliminated from the diet and environment until the cause is resolved.

Dog and Cat Allergies – A Natural Approach
A very common problem in dogs and cats are allergic reactions that are persistent, difficult to suppress, and often the only solution offered is corticosteroids, which sometimes help and sometimes don’t. In the end, we have a vicious cycle of recurring allergies and a compromised immune system due to corticosteroid use, masked and secondary inflammation.
A Different Perspective on Allergies and Therapy
My experience has shown that internal conditions or diseases causing allergic reactions are usually not discovered, or their causes are difficult to find. Therapies typically involve immunosuppressive drugs to prevent the body’s reaction from ‘showing’ that something is happening, as well as corticosteroids for more severe reactions with skin inflammation. This is fine if it helps once and the reaction doesn’t return. But what if it persistently recurs? A solution should be sought in a different way. The natural approach you can try is not harmful, does not interfere if the animal is already on some therapies, and is worth trying if you are struggling with this problem.
