So you need to know about the dog? Kojak, the dog, is left behind because they leave on motorbikes. By himself. I know. He isn't mentioned again he just shows up asleep on a porch later. We learn he'd travelled, on foot, alone, for miles and miles to get back to Glen. He took on a pack of evil wolves and won. He is a hero and goes on to the stand. Stephen king kindly let's us know when kojak comes back that he survives to be 16 and goes on to be a doggy daddy. So you're able to relax then
