Please. Take NO chances. Now you must completely control the environment. Gate, crate, and rotate. Everything the other posters suggested too, but the "can't be there all the time" thought has to go. It is now YOUR responsibility to PROTECT all members of your pack. If you don't you will have a dead or badly injured dog. Please take this very seriously and do not allow another "accident" to happen. Please.
