Wow, BatterseaBrindl, HeyRunDog, and greysmom, thank you so much for all of the advice!!
Today, my boy seemed so happy outside and then we took a 0.75ish (I approximate I’m not measuring or anything😂) walk on sidewalk/grass area. He seemed so happy. I think he is starting to settle in (been about a week since he came).
Being patient (have not brought in another dog yet) and hope he continues to be happy outside.
I will keep you updated. Thank you for the help, I cherished it and it was so helpful!!
