Thank you for your response! She seems to be a very good girl! I did all of the above we went for a walk first if she started focusing on something I would redirect her make her sit had an entire bag of treats handy! Once we walked and I felt I was very much in control we went to take a trip to petsmart. Car rides seem to make her anxious she whined so we stopped at a park I let her out we walked sat hung out some more and this time she needed minimal help getting into the car. We made it to busy petsmart. She was a good girl no vocalist ions what so ever we hung out outside she walked up wagging and licking at a couple people ignored the dogs. She was not ready to go inside so we left hoped right in the car. I plan on bringing her home this weekend and am praying for an easy transition!!!
She sounds lovely! I have fostered dogs for 30-some years and my general protocol is to take the existing dogs for a good long walk and give them tons of attention before bringing new dog home. Then when I get home, existing dogs get lots of happy greetings and treats and let outside, then new dog comes in, gets to walk around the house for about five minutes, then into a crate. Existing dogs then get to come back inside one at a time (so there is no pile-on) and we take it from there. If I'm not sure about new dog and cats I keep it on a leash and watch body language.
Food, toys and everything else of value (to the dogs) is put away so there are no possession or jealousy issues. I also make sure new dog understands that it is at the bottom of the pile, status-wise, at least initially. Fed last, not allowed on furniture, etc. Dog has to earn privileges. I hope your new girl does great!
