Welcome to At Peace Pets, based in O’Fallon, Missouri. If you’re here, it’s likely that you’re thinking about making a difficult decision for your pet. We’d like to help. Please take your questions and concerns and look around. If you just need to talk with someone, please contact us and we can discuss your concerns further. We love pets too, and in a time of need are here to provide dignity and peace in a private, familiar environment — the home.
