Amanda, I am so so sorry to read about your Bentley
You're probably doing everything you can possibly think of, but if I were in your position, I would be posting a pretty decent-sized reward, no questions asked at this point. I'm sure you would do anything you could to have your baby back, so please do that and hopefully someone will return him.
I went to see if any had been posted on Craigslist as found, but I see you already beat me to it and posted missing ads on there as well. Just KEEP LOOKING if he hasn't been found yet...don't give up! I hope he was microchipped....we are praying sooooo hard you find Mr. Bentley...hopefully he's already been found and you just haven't had a chance to update yet!
