Oh, that is wonderful!! Some dogs just know when to make that connection & who knows their reasons? It's a very healing thing.
I volunteer with special needs adults, many of whom are non-verbal, autistic & such. Lexie is always with me, so she cuddles up with the most shy and debilitated people. it doesn't seem like a chore to her at all, as long as they are physically gentle. As a matter of fact, as soon as I get off the freeway exit to go there, she starts barking & bouncing around knowing where she's going. So excited! It's a Lexie Love-fest!
