We have been impressed with Trevor in the short time we have known him. He is quiet, seems patient, and did well when meeting other dogs that his animal shelter tested him with. In a kennel near our main meet-and-greet area, Trevor observed all of the goings-on but didn't vocalize about them. He's estimated to be 4 years old, and he's currently underweight from his animal shelter stay but should reach a healthy weight in the lower 70's.
