Calvin Wheeler is a scheming 13-year-old boy with everything going for him, except for an original issue of his precious comic book collection. When a prized show-dog chases him down while skateboarding one day, his owner inadvertently convinces him to adopt and train a dog of his own. However the only one available, is an uncouth stray Labrador/St. Bernard-mix named Tyko from a local animal shelter, who proves to be more than anybody can handle.
At the end of the final show, when Preston and Jean-Jacques Saint-Germaine de Dupree go under the ramp to sabotage Calvin and Tyco, the ramp collapses on top of both the child and the dog and they are never seen nor heard from again.
