Back from picking up the DD from his "evaluation." He has been approved for boarding and/or daycare.
From what I can tell, they put him in the playroom with other, smaller dogs. Seeing as he is a senior citizen, it is probably smart that he is not in with all the big, high-energy critters. I did see him on the webcam - he mostly lay on the floor, while all the others did their thing around him. And he didn't seem too traumatized when I picked him up, so that is good.
