Hi there and welcome to YT with your new little rescue.

To me it sounds like Toby just needs a little more time to adjust to her new environment. If his foster mom told you that he was trained, liked to cuddle etc just give him time. When I first brought Bogey home from the shelter a little over a year ago he was a total spaz, didn't know what it was like to be picked up and help, how to do stairs, what grass what, how to ride in a car, potty outside ALL the time, the list could go on forever!

Now he is laying in my arms sleeping while I am typing this to you.

It will take time for him to adjust to you and his new home.
Here is a link to an excellent article that was made a sticky in the rescue and also training forum:

I would like to suggest that for his potty issues, that you purchase BELLY BANDS and put him in one right when he walks back into the house. It is hard IMO with puppy-mill rescues to use a crate because some are traumatized by being put into that environment again. The above article addresses some of this as well and offers more suggestions.
As for "scolding" him for potty accidents this is never a good idea even if he was not a rescue. If you are giving him treats for potty, you need to be standing next to him to reward with a treat otherwise he will not associate the treat and potty. If he comes into the house after potty he will only associate the treat with coming into the house.
If you would like to try to make him your little lap dog, I would suggest that you go to him on the floor instead of trying to make him come to you. Sit on the floor with a few treats and allow him to come over and treat and praise.
It will take a lot of time and some effort to make him comfortable in his new forever home.
To this day Bogey will still run if anyone raises their voice. Good luck and if you need any more help please PM me. I will do as much as I can to help you and Toby through any rough spots.
