I can certainly see the benefit of a meet and greet in home to make sure that they can get along with other animals in the house. But as many other members have pointed out, it doesn't tell you much about the dog beyond that because it takes a long time for them to settle in. Behavior will change as they become more confident, and the dog you have for life may seem very little like the anxious mess you brought home. Trust can't be built in a day.
Same goes for training... it takes time and WORK. But the bond you form with your dog while putting in all that work is priceless.
I understand that these weren't your choices, and it breaks my heart not just for the shelter dogs, but also for you having to give up your puppy. But just because it's not fair doesn't mean you can't learn something from it. I hope you will remember the advice of the other members when you do eventually get another chance at owning a dog.
I truly wish you all the best.
how old is he now?
