✅ What To Do If Your Pet Eats a Toxic Food
🐾 What to Do if Your Dog or Cat Ate Something Toxic 🐾
If your dog or cat got into food toxicity, act fast! 🚨 Many human foods—like chocolate, grapes, onions, garlic, and xylitol—can be deadly to pets. The first step is to remove any remaining food, check your pet’s mouth, and call your vet or emergency pet hotline immediately. Do not induce vomiting unless directed by a veterinarian, as some toxins cause more harm coming back up.
