The therapist suggested anti anxiety meds. But the dog is already depressed. What is your opinion on medicatin?

I adopted a 4 year old German Shepherd that was taken from a puppy mill. Her whole demeanor made you feel that she felt beaten down by life, not physically, but beaten down in the sense that she had never know any of the joys of being a dog, and she felt it was better to be shy and quiet and not draw attention to herself. She was shy, quiet, fearful, and completely lacking any confidence. She was scared of everything, especially in the house. For the first 6 months it was almost like not having a dog at all. Even though she wasn't confined to her crate, she spent almost all her time there because to her it was a "safe" place. She stayed in her crate in the bedroom, would dash through the living room to the kitchen if I was cooking, and then dash back to her crate. The sound of the TV scared her, if my cats made noise it scared her, if I made any noise it scared her, everything scared her. It took a long time, and a lot of patience and praise, for her to gain any self confidence. I'm talking a long time, as in over a year before I really began to see a change in her. But once she started getting some self confidence, she blossomed! She learned how to play, how to bark, how to have fun, and became that tail wagging, lick your hand, dog that you're hoping to get. We went on through advanced obedience classes, and everybody absolutely loved her. People who saw her when I got her, couldn't believe how she turned out. I was so proud of her! My point here is not to brag on my dog, but to tell you that with love, patience, and positive reinforcement, we can help these dogs so much. It takes time, time, time, and 8 weeks is nothing in the timescale for dogs like this. Just don't give up. Sadly, I had to have my dog put down due to severe hip dysplasia, but those problems are common in puppy mill dogs, unfortunately. But I have a new dog with some of the same confidence problems and fears my GSD had, and we're working on those together now. Your dog has so many of the problems mine did, right down to the not eating well, and not barking. I wish I could sit down with you and talk in more detail, but my best advice is to prepare to take the long haul with your dog. The rewards will be great for both of you. Best of luck to you and your dog.
