Keep your products up and away. Any cleanser you use here could be fatal, too.
Many dogs eat bar soap, and that can be toxic, too.
For the record, Cleo and Helio are my bar soap eaters. Flea soap and other shampoos can have the same 'good smell' liability. Even canine vitamins can cause liver or kidney toxicity should your pooch decide to eat the whole batch. And more than one dog has made himself extremely ill by eating a whole bag of dog food he happened upon. For those of you in cold weather climates, a big concern in anti-freeze.
