The duration of a dog's allergic reaction can range from a few hours to several weeks, depending on the factors mentioned above.
In general, mild reactions may last for a day or two, while more severe reactions can persist for up to two weeks or longer.
If the trigger is removed and appropriate treatment is provided, most allergic reactions in dogs will resolve within 7-10 days.
However, in some cases, the reaction may be more prolonged, especially if the trigger is not identified or if the dog's immune system remains highly sensitized.
The duration of a dog's allergic reaction can vary widely depending on several factors, including: Trigger Exposure: If your dog continues to be exposed to the allergen, the reaction may persist or worsen.
Removing the trigger is crucial for managing the reaction.
The speed and effectiveness of the treatment, whether it's medication, dietary changes, or environmental adjustments, can impact the duration of the reaction.
Each dog's immune system and overall health can play a role in how quickly they recover from an allergic episode.

Dog food allergies can take anywhere from 2 weeks to 2 months to fully clear up, depending on factors like the severity of the allergy, how long your dog has been exposed to the allergen, and how quickly you remove it from their diet. While some symptoms like vomiting or diarrhoea may improve within days, more persistent issues like itchy skin or ear infections often take longer to resolve. Some dogs show improvement in acute symptoms like vomiting or diarrhoea within 24–48 hours of removing the allergen. Symptoms like itchiness, redness, or rashes can take much longer—typically between 2–4 weeks. More severe problems like ear infections, yeast overgrowth, or secondary bacterial infections may take 4–8 weeks to fully resolve, especially if they require antibiotics or other medications. Most dogs will show visible improvement by week 2 or 3. For full recovery, it’s crucial to follow through with the diet until all symptoms are gone. Stick to this diet for at least 8–12 weeks to give the body time to fully detox.
