Hi Gina
So sorry to hear your having a few problems with Barkley
I just wanted to let you know that I have also been through this, with my old GSD rescue "Sheba" she came to us at the age of 4 1/2 and was in a terrible state both emotionally and physically, she had a lot of health issues that we managed to sort with medication. However, the emotional side of it was the hard bit! She started howling the minute there was noone in the house :roll: she was scared, she had had so many different homes and been dumped so many times
She was basically an insecure dog through no fault of her own, her howls where cries for help! The neighbours soon got fed up, and started to complain :roll: which I suppose I couldn't blame them really, I had to do something about it, or it would mean yet another home for Sheba :cry:
I had a pet behaviourist come out, who although was good, she didn't really give me any other advise, that I hadn't already tried :? The leaving for very short periods of time, basically I would put my coat on, and you could almost see the sadness in Shebas eyes, that she knew she was going to be alone :wink: then I would move to the door, open and close it and go back in, then I would actually go through the door for literally a few minutes, come back in, I made the times longer and longer, I would say nothing to her atall, not even look at her, although it was really hard for me not to
I did this over about 2 weeks, increasing the times and inbetween mum would go in and see to her too
It was very hard work, and at first I thought it wasn't going to work :roll: But she started to improve, she would still howl for about 5 mins after I left but then would stop, I used to walk up and down outside to see if I could hear her :oops: It was heartbreaking to hear her, but in the long run this was going to benefit her as much me and of course the neighbours
To cut to the chase she improved about 75% which was not perfect but was certainly a great achievement on her part, she had gained trust back, and realised that she can cope without me and vice versa
What I am trying to say is stick with Barkley follow some advise, either from your vet or from boards like this one, things are sure to improve with Barkley in time, hes maybe thinking that he just can't be without you for a second, teach him he can, it takes time, patience and tears, you will get there eventually
Good luck with it, please let me know how you get on
