I feel like the worst dog/human mom ever

Long story short...pipe in the kitchen got a leak and while my mom and I were putting a bucket under the sink, Zoe licked the puddle of water which had draino in it! I gave her some milk and water, and my mom ran her to the Vet. I hate myself

I think I caught her right away, but I worry since she is small. Why me? If anything happens to her I'll never forgive myself
