I'm so sorry. Iker was started on Clomicalm last year; 40mg. He did terribly on it and was taken off fairly quickly. He stopped eating and never got up. I started him on it again last month, starting with 10mg and increasing it by 10mg every two weeks. We're up to 30 now and he is doing really well. Maybe a gradual increase might work?
He sounds like Iker. I can't take him for a walk if there are any signs of people anyplace, even with the Clomicalm. He got away from me twice, and ran straight to my front door both times. He is happiest in my room, where he feels safe, just like you've described Zhivaya. He is afraid of kids, bicycles, men, cars, trains, you name it. I think sometimes we just have to accept their personalities and love them for who they are, not who we wish they were (I'm not saying that you're doing, i mean in general).
I had a great session with an animal behaviourist via Skype. She suggested that I was starting desensitization in steps that were too big. She had me start to toss treats to Iker while he was comfortable and laying down. Every time I changed, like stood up, I tossed him more. Eventually I will start to toss him treats as we leave the house, but we haven't gotten that far yet.
