But beneath all that beauty, there are a few **less obvious risks** that many dog owners (especially newcomers) don’t see coming. Knowing what to look out for can make the difference between a great walk and an emergency vet visit. --- ## **1. Pine Processionary Caterpillars (High Risk)** These are one of the **most dangerous hazards** for dogs in Portugal. They appear in: * Pine forests * Woodland trails * Warmer months (typically late winter to spring) ### **Why they’re dangerous:** Their tiny hairs contain a toxin that can cause: * Severe swelling of the mouth and tongue * Vomiting * Difficulty breathing * Tissue damage (in serious cases) ### **What to look for:** * Caterpillars moving in a line (procession) * Nests in pine trees (silk-like bundles) --- ## **2. Grass Seeds (Foxtails)** Small, sharp, and incredibly problematic. They’re common in: * Dry grasslands * Trail edges * Late spring and summer ### **Why they’re dangerous:** They can lodge in: * Noses * Ears * Eyes * Between toes --- ## **Final Thoughts** Walking your dog in the Algarve can be one of the best parts of living or visiting here.
