Pets are a wonderful thing to many people. They are close companions, they're loyal, they sometimes save their owner's lives, and they relate to people on an emotional level that is different from connections with other humans. But for every pet owner there is a first pet. And it is a real learning experience. It turns out pets aren't just shiny new toys. They are a huge responsibilty. They need attention, they make messes, they can get in your way, they need to be cared for on a regular schedule, they cost money in food and veterinary bills, and they are always full of surprises. All of this tends to come as a shock to first-time pet-owners. This is a story which focuses on the main character or characters getting a pet and dealing with all the problems and joys that come along with it, usually being completely unprepared for what they get. In most stories, there is a happy ending in which the owners get the hang of this pet-owning thing, and welcome a new and beloved member into the family. Sometimes however, they realize that they either can't cope or aren't committed enough, and the animal has to go. If the person getting the new pet is a small child, expect it to be either a goldfish or a puppy. Goldfish are popular choices for savvy parents because the little creatures take up almost no space and are very low-maintenance. Unfortunately, they also have a fairly short life-expectancy, and are likely to die if fed improperly or if the bowl isn't cleaned out frequently enough. Expect a Dead Pet Sketch to follow, and this scenario is even the trope namer for the Replacement Goldfish trope. Puppies on the other hand, are the most often requested by the child in question, and are also among the highest maintenance. They are energetic, messy, loud, in constant need of attention, and typically require a lot of training. But they're just so cute! However, despite all the problems, the characters will often find that the pet is a joy unlike any they have ever known. They have found a creature who is loving and loveable, and quickly makes itself part of the family. Maybe the animal even completes them in some way, opening them up emotionally or teaching them responsibilty and patience. They will probably be surprised to find how hard it would be if they lost the animal. Truth in Television in that many people are unprepared the first time they bring an animal into their lives. People also have a tendency not to figure out what would be a good kind of pet before getting one. Large working breeds of dog typically don't get on very well in a tiny apartment. Unfortunately, Real Life also has a lot more people who decide the pet just isn't worth the hassle, and dump it on the streets or in a shelter. Just because a character has a pet and it happens to be their first does not qualify as this trope. There needs to be a significant focus on dealing with learning how to care for and love the animal. May overlap with A Boy and His X or Pony Tale. May include instances of Artistic License – Animal Care, depending on how accurate the author is being.
- In Beethoven a boisterous St. Bernard is adopted by the Newton family.
- Lilo & Stitch has elements of this. Lilo expects a dog to drink out of a baby bottle and sleep in a doll bed, and Nani is inclined to return him to the pound when things don't seem to be working out. Stitch, however, is not a normal pet, so most of the incidents in the movie are not consistent with what would happen getting a real dog.
