My dog has a genuinely insane resistance to poison

She’s 12 years old and she got into a bag of raisins, ate probably a half cup of them, and didn’t throw up at all. She’s fine. This was over 3 months ago. She’s eaten rat poison, shit tons of chocolate, she’s even eaten toothpaste with xylitol in it. We’ve learned to be way more careful with things dogs are vulnerable to but she’s genuinely just insanely strong on the inside. Just felt like sharing because she’s an awesome dog. And I am still just as careful with toxins as I am with my other dog. Every time she’s eaten something, We try hydrogen peroxide and she usually just tanks that too. Just love her and felt like sharing her coolness
