Little Dogs Lost

Little Dogs Lost is the one hundred and thirty ninth episode from Season 1.

Plot
Dennis and Ruff are bored, until they see Gina trying hard to walk her dog Garibaldi. Gina wishes she didn't have to walk her dog every day because he wears her out. This gives Dennis an idea; Walk Garibaldi for Gina, as well as walking other kids' dogs. A dog walking business. As soon as he hires other dogs, Gina has doubts about Dennis' idea. Tommy has his doubts too, but Dennis claims he can do it because he likes dogs more than peanut butter and jelly sandwiches.

As Margaret walks along with her cat, Ruff sees them, and tries to warn Dennis, but to no avail. Dennis doesn't realize until too late, that Margaret was walking her cat, and then the dogs chase after it. In the process, as they all run past Margaret, she passes out from her dizziness.

While chasing Margaret's cat, the dogs break through a fence and shatter Mr. Wilson's brick barbecue in the process. Dennis unintentionally lets the dogs go. He then organizes a search party. Tommy is to search Elm Street, Gina is to search a maple tree, Maria's to search a pecan tree, and Lars is to search a fig tree. They have to also search for every bush and fire hydrant.

Dennis and Ruff agree to search Main Street for the goofy dogs. At a beauty salon, they find Lars' poodle. At a sausage factory, they find Maria's dachshund. At the park, they find Tommy's boxer, who is literally boxing. Dennis and Ruff return the dogs they found to their respectful owners, but there's one dog missing; Gina's dog Garibaldi.

Ruff gets the idea as to where Garibaldi could be. This prompts Dennis, Gina, Maria, Tommy, and Lars to follow Ruff along with their dogs. They eventually find Garibaldi at a cafe slurping spaghetti. Now that the search is over, Dennis agrees to relax. Tommy is about to agree with Dennis until he sees Margaret and her cat again.

The dogs start to trash the cafe and run out of it to chase Margaret's cat again. Dennis decides to organize another search party to find the dogs again. Dennis agrees to allow Ruff to lead the search party again. This prompts Ruff to faint.
