More: Tank has endless amounts of energy. He is 90 pounds of pure joy and the biggest softie. He loves playing with his toys and his favorite toy is a Wiggle Waggle ball. He swiffers it across the floor with a duck toy and can play like that for 30 minutes plus, leaving him completely worn out. He loves to visit dog parks and has lots of friends. Most of all, he has completed our family and we love his endlessly.
