Answer

How dangerous are processionary caterpillars in Mallorca for people and dogs?

Processionary caterpillars in Mallorca can cause strong inflammatory reactions if their stinging hairs touch skin, eyes, or the mouth. Dogs are especially vulnerable because they may sniff or lick the caterpillars, and puppies can react badly very quickly. Contact should be treated as a health concern, not a minor irritation.
