When I adopted my now crazy, fun loving insane Chloe, the BIOTCH, she was a spook who had been returned. Oh the things that would freak her out. My DH would have to crawl on the floor on his knees to get to her. He did and now of course she is daddy's girl. She could not be outside walking if there were bicycles, garbage cans on the street, our shadows freaked her out, my DS... oh you name it.
it took time, patience and lot of love!
Now, over 2 years later, sometimes Chloe will be the only dog we bring to meet and greets. We laugh amongst oursleves that our Chloe, the once spook is doing m&g alone!!!! Reason being, Teddy can get aggressive, Beau HATES M&G even though he is so social, he's too ADD to stand there and it's too much for Polli so we bring Chloe!
She does greyt.
Also, the more you can bring her to social events will help her become more comfortable.
