The doggies play and have fun, while the Best Ber only sees his new friend chasing his tail, rolling around in the grass, and doing general dog stuff.  The old friend approves of the new dog and passes the dewlap torch.  The Best Ber always thought the two dogs would get along if they had the chance to meet!  Back up Rainbow Bridge the old friend goes, where he will watch down on The Best Ber.
