I texted my son today to check on Toby. He said the dog laid by the door I went out when I left until my son had to leave for an eye doctor appointment. Then he let the dog out and put him in his crate. When he got home and let the dog out of the crate, the dog ran around the house all excited and happy. My son played fetch with him. Then later my daughter in law and granddaughter played fetch with him.
This morning Toby didn't want to go out to pee because it was raining. My son walked him around the backyard holding an umbrella over the dog.
Toby is getting lots of attention and seems happy there. I'm going to try to stay away for a while so he will bond with his new, permanent family. They already love Toby. And I love him and miss him, too.
