Sea Dog

When Kyle finds a young dog almost drowned in a heap of seaweed on the beach, he claims the dog as his own and is happy for the first time in a while. He knows that his dog loves him, but whenever they walk on the beach, the dog swims out to sea and doesn't come back until Kyle calls and calls. Then one day, they run into an old man and it turns out that the dog may not belong to Kyle alone.
