More: This big chocolate boy is keeping cool in the Texas heat with weekly visits to Bill Archer Dog Park, a 17-acre park with swimming ponds and walking trails. Knox is half English, half American weighing in at almost 90 lbs. He is big in size and sweet in demeanor. He stays active with daily walks, chasing squirrels, agility courses, swimming in any and all bodies of water, and loves to relax on his favorite Orvis bolster bed. A true Orvis boy!
