I'm happy you and Connor found eachother.
She said just be firm with NO, crate him if I can't watch him all of the time until he settles in, and if he does it, give him a time out in his crate.
I agree with the beginning, but not the end of this advice. Dogs don't get the concept of "punishment after the fact" because they live in the moment. In fact, punishing a dog for reasons unbenownst to them is very likely to cause anxiety. And it sounds like this dog is very anxious, and understandably so given his background.
It's going to take some time for him to learn a new way of life with you. Two words of advice: Exercise and Routine. Predictability lessens anxiety in anxious dogs. Medication should not be necessary right now - just love and patience. Also, all interactions should be CALM and assertive with a dog like this, not loud and/or threatening (not that you would deliberately be that way; I'm talking more in his perception).
I would treat him almost like a puppy learning housetraining. Take him out frequently and show him what you want him to do. Praise when he does. Constant supervision (which should not be difficult given your description of him

) should allow you to catch any "accidents" as they happen or even BEFORE they happen. If you see him motioning to pee in the house, or actually going, that's the time to show him what you WANT him to do, ie run him outside and praise. Knowing how smart these dogs are, he will understand in no time.
I think it's a great idea to get him some of his own things. It sounds like he hasn't really enjoyed that before, and it's high time he has. Some handsome new bandanas, a new bed, a few new toys, maybe a nice coat for the cold weather, etc, should make him feel pretty special.

They get it.
A friend of my DH's and his wife adopted a dog around Thanksgiving. The dog is very anxious and afraid of men. He wanted so badly for the dog to like him, but my DH told him it was going to take some time, that he had to develop a trust first. The dog actually bit him when they first brought it home because he tried too much too soon. So he backed off. He was there, but instead of going to the dog, he lets the dog come to him. It's been 3 months now, and we just got a report that the dog is finally beginning to come to him on his own with a little tail wag. Progress.
My dog is, by nature, quite anxious. It's taken an extraordinary amount of time and effort to get her to where she is today. Most people meet her and comment on what a great dog she is, saying "I wish my dog was that good". They have no idea what it took to get there - they think she just came that way!
My sense is that Connor is going to thrive in his new home and a year from now, you'll hardly recognize him as the same dog he is today. Good luck.
