Runs like Dog

He's not being medically treated correctly. The VA or their referral is punting. He's on the wrong meds at incorrect dosage. You need to have him sent to a different psychiatrist.

FWIW I would also explore less traditional medical regimens in adjunct. Meditation, Tai-Chi, Some types of yoga and acupuncture.

And since I am trying to create some therapy dogs, I would contact whomever you can locally to find out if there are any therapy dog programs near you. Therapy animals are becoming more mainstream as the facts roll in that they're useful.

The outside of a dog is great for the inside of a man.
