They can be severe and life-threatening or milder. On average one in five children can outgrow peanut allergies, but most children do not.
Children with peanut allergies can be desensitized to peanuts and peanut products via several methods. One of the most common methods is called oral immunotherapy which introduces small amounts of peanut protein by mouth daily, with bi-weekly or monthly increases of the dose of the peanut protein.

I strongly encourage you to consider peanut desensitization with your local healthcare specialist, as it can be life-changing

Are Avil and Cetrizine the same when it comes to treating an allergic reaction?

If you mean Advil and not Avil, then no. Advil is ibuprofen, a pain reliever and antiinflammatory medication (NSAID). Cetirizine is a second generation, non-sedating (usually) antihistamine. Most common side effects are minimal. With cetirizine, it can make you feel tired or sleepy and it could dry out your mucus membranes. For Advil, the most common side effects are limited to GI symptoms, but it can have effects on your kidneys if taken longer.
Addendum: just looked up Avil and in Australia, Avil is a brand of pheniramine maleate, which is a first generation antihistamine. It can and might make your aunt sleepy. For other side effects, I would look on the package insert. Hope this information helps.

Yes. You can do allergy testing on a 3 year-old. The better question is SHOULD you do allergy testing. He may not be allergic now, and may never be allergic to dogs.

That is very important.
