Anxiety/Stress Help

[mejab]

We are working on this situation with our vet, but I was wondering what other people's experience has been with treating anxiety in their dogs

My rescue Rott has been having bouts of stress/anxiety where he will not settle down, and he is generally stressed out for several hours, and will pant constantly, and try to hide in corners (behind the toilet for example,) or he'll want to be right next to us (or on top of us.) He is also deaf, so we are not sure if something is going on with his "hearing" or ears in some way. I think he just exhausts himself doing this.

I have tried Bach Rescue Remedy, and I know that there are some other Bach remedies out there, but the Rescue Remedy is not really working.

Has anyone used any meds such as Xanax for this type of stress/anxiety?

Thank you for any input.
