UPDATE

FOSTER UPDATE- DAY ONE: It looks like Yankee is doing excellent after just one day.  According to his foster, We let him play in the yard most of the afternoon and kept him on a leash in the house following us around. Yankee got through the night okay after we put treats in the crate during the day and at bedtime as an enticement to enter.  After we closed the door,  he fussed a bit but then settled down.   I slept downstairs in the same room.  He slept all night but the cone kept banging on the sides of the crate.  Tonight I will leave him and go back to my own bed,

On this morning’s walk, he was very curious. stopping to watch bikes, runners, and other dogs.  He didn’t pull nor bark-We haven’t met other dogs close up yet. 
He likes to be near people and appears to want to please which is always such a positive trait.
