One night last year I had put the dogs out in the garage to eat as usual. Lilly apparently finished early, wandered away from the food bowl and managed to dump an entire box of pool chemicals. I found her licking up Ph adjustor. I screamed, grabbed her and the bottle and frantically called the emergency vet. We ended up having to bring her in. It was an absolulte nightmare, but thank god she was alright. Now all the chemicals are locked in the shed.
