I wanted to get any thoughts and advice on using e collars that vibrate or shock to help with unwanted barking when you are not at home
please Don't get one they are cruel and unnecessary. They will hurt your dog and relationship with your dog and diminish you as a person.
Don't use one. They're unethical. You'll end up with a neurotic and scared dog. Do tell us about the barking issue though - maybe we can help with some training or management advice that will work
They are illegal in many countries for good reason; they are cruel and unnecessary.

Members may not advise others to use painful punishments on their dogs, nor promote the use of punishment in dog training by posting anecdotes which endorse the use of such punishment. I echo Rachael - give us some more information and let's see if we can help find a better solution.
