I definitely feel your pain! It's tough to say exactly what the next step is here, some more info might let us help you better. What is your and Brodi's schedule? Do you have a work schedule? Are you home a lot? How often is Brodi left alone? How long have you had him? Is Chloe crated?
Definitely sounds like SA, it's not a crate issue because he reacted the same way in the bathroom. Basically, the way to break this cycle starts even when you are home. You have to get Brodi to be comfortable enough alone in a room. I would forget the crate for now, its just a bad experience for him at this point. Don't let him be with you all the time. You don't have to leave the house, just leave the room/close the door. Start with 1 minute. Move up to 5 minutes. So on and so on. You get to the point where Brodi is able to chill out in the house without being next to you. Once he's comfortable with an hour or so, you can try leaving the house. Start small, check the mail, take out the trash, etc. The key is to return before his anxiety kicks in. If he's already at the panting/drooling stage, you were gone too long and try quicker times. Once you work up to 10 minutes alone, you can go for a drive for 20 mins. Ignore Brodi when you leave, and when you get back. Don't make a big deal out of greetings. Make it seem like you leave the all the time, and he won't be as anxious. Once you can leave him for 30 mins and he's ok, you are most likely on your way to freedom. SA is said to be at its worst within the first 30 minutes.
All of these exercises work best when the dog is tired. Get him exhausted. If he sleeps when you're not around, that is huge. Dogs are less anxious when they are tired, and if you can get him tired and sleep while you're gone, suddenly being alone isn't a bad experience. Doggie daycare can really help with this stuff too, even just once a week. It helped Oggie a lot. Without knowing any more of the background info, thats my advice for now. Let me know if theres more to the story. Good luck!
