I know, it is a strange way to say hello but dawgs do that. They get so much from smelling.
Check out 'A Sense of Smell'
They can tell where you have been, what and who you have come in contact with etc.
It's amazing.
Red came to visit and he was not over the top excited. Yes, he was excited but not crazy excited. That tells me he rather likes his new home and that makes me happy.
Raylan was a tad jealous but Red didn't pay him any mind and now Raylan is not following him around like he is his glove to be worn.
It's so great to see the Red!
They do enjoy each other and this visit is good for them both.
