My 10 month old puppy had an accident on my carpet on a wednesday. i cleaned it with a carpet spot and stain remover that said it would get out pet stains. i sprayed about 7 areas on the carpet and used a damp sponge to rub it in. her crate is in the same room. on friday when i got her up, she was totally blind. she has been to the vet and a specialist and is recovering slowly. her eyesight is coming back, but her spirit is taking a bit longer. the chemical in the cleaner was 2-butoxyethanol, but i don't know what else was in the cleaner. i recommend that if you have pets or children you only use totally safe products. read the label. this label said nothing about harming pets, but i believe it is what caused her temporary blindness. buy the expensive stuff, it's well worth it. learn from my stupdity.
