I do not personally support debarking, but nor do I find it inhumane if it's necessary.

If you decide not to rehome the dog, I suggest you try to work out the reason he's barking before even considering debarking him. If it's seperation anxiety, boredom etc, debarking would not solve the problem at all.

If you tell us more about your situation, we might be able to help you more. Information like below might help explain the reason behind his barking more
1. When does he bark(Is it only when you're away etc)
2. Has it been a recent problem? Or since you got him? If so, since when?
3. How much physical/mental stimulation do you give your dog daily?

Divas is right. Do a bit of research online and you will find she is not lying or making things up. She is just concerned about your dog, not trying to have a go at you.
