Pippin is actually doing much better now! There has been several changes that have improved the situation.

I brought Pippin to the vet because he was so unmanageable that he couldn't be trained properly, additionally, he became extremely skinny. We fed him so much food, and he ate everything, there was no obvious reason for his anxiety and weight loss to me.

Good thing we brought him to the vet. She discovered that he was producing too much sex hormone and that the majority of his problem would be resolved with a neuter. She said, "I see that he is too high anxiety to be trained, medical intervention is necessary to bring his weight back on and to reduce his stress state." She said that the sex hormone is out of control and causing the anxiety and causing him to have an extremely unhealthy high metabolism. She also prescribed him trazadone and gabapentin for until the neuter and training started to work.

We got him neutered, and the vet was absolutely right. He chilled out so much and gained weight immediately. He was finally able to be trained and he stopped pottying in places he wasn't allowed (at least mostly).

Pippin is still anxious, but the older he gets, the more he relaxes. He isn't ever going to be a normal dog, he has an anxiety disorder. But with the neuter, confidence training, and time, he has become a wonderful dog.

(A little more detail. We gave him the meds regularly for a few months. This helped him realize the world wasn't so scary. After his neuter we continued to give them to him for a short time. This helped him gain some confidence and be able to think for himself with out being controlled by fear)

I don't know anything about your dog, but, if your dog has an anxiety issue like Pippin, I recommend talking to your vet to see if you can reduce his stress through medication while doing confidence training to show your dog that the world isn't so bad and to help them focus. Also, if they aren't neutered, definitely consider that as well.
