Very social

Arrived with my 20lb miniWhoodle. Staff friendly and asked appropriate questions. My pup likes, actually prefers, new or familiar, big dogs so they left him in larger area to play. When I got back about 3 hours later, pup was in front with tiny dogs. They told me he didn't do well with the big dogs. This has never happened before and he was a bit skittish for a week or so after. Not sure what happened, but something wasn't right.
