Dunsparce is a very easy Pokemon to take care of. They are herbivores, and so food is easy to find. They prefer berries, but a simple bowl of salad will do find for a meal for them. They’re also slow and relatively small, so its not like they’ll ever make a mess, at least not indoors. They really love attention too, so be sure to give your Dunsparce lots of pets!

One thing you really have to look out for though, is Dunsparce’s habit of digging holes. While it won’t do this in a house, if you’re outside, it will surely attempt to burrow through the dirt. If you have your Dunsparce at home, then you need to train them to know that they are not allowed to dig in the garden! This can be difficult, as digging comes so naturally to them, but with enough positive reinforcement, they should get the idea. If you’re a travelling trainer, then it might be okay to allow your Dunsparce to dig if you’re out in the wilds. Just be sure that they don’t do it somewhere that’s very public; as the hole would be a massive safety hazard, and you could face a hefty fine.
