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.
Many brands still taste sweet to dogs, and ingested in even small amounts, it is fatal.
Boxers love toys, and if your dogs are anything like mine, toys are ALL around the house. You've probably stubbed your bare toes about a thousand times, but that's not the safety aspect we're concerned with just now. This can cause gastric distress, and sometimes choking. Again, Boxers love them, and they can provide a lot of chewing enjoyment. However, when they get smaller, both tend to splinter and can become dangerous, small pieces.
