Rockruff (イワンコ, Iwanko) is a rock-type Pokémon introduced in Generation VII.



Rockruff is a small Pokémon that resembles a slightly plump dog. It has a fluffy tail, brown paws (with a small triangle on their end of the legs), a white neck decorated with brown fragments, a somewhat fatty beige underbelly, a brown mouth with a pink nose, two blue eyes and a pair of brown lowered ears. Ears are similar to those of a fox when they stand up.

Rockruff like to show their affection by hitting the rocks onto their Trainers. Unfortunately, this may make their Trainers feel painful. However, they usually become fierce during the time they grow older, and howl at evenings when they are going to evolve into Lycanroc. When they know that they will evolve, they might leave their Trainers for a while until their evolutions are completed.There are tales of it reuniting with its Trainer after becoming lost by following the faintest traces of scent. It has lived with humans since ancient times. Rockruff is often recommended as a good beginner due to its friendly nature. It can bond with Trainers easily. However, Rockruff is said to be a challenging Pokémon to raise, to the point where some Trainers abandon it due to being unable to handle it. This Pokémon is very sociable and will greet others by rubbing them with the rocks around its neck. Rockruff intimidates opponents by using the rocks on its neck to hit the ground. As mentioned in the anime, Rockruff trains itself by running around. It attacks foes the moment they flinch. It has been known to fight with Growlithe over territory.

Natural abilities

Rockruff has an excellent nose that makes it won't forget the smell it sniffed before.


At level 25 or over, Rockruff evolves into Lycanroc Midday Form during the daytime, and into Lycanroc Midnight during the nighttime.

If a Rockruff has Own Tempo as its Ability, it can also evolve into Lycanroc Dusk Form during the Evening Twilight time (7:00 p.m. to 8:00 p.m.)

Pokédex entries

  • Sun

    It’s considered to be a good Pokémon for beginners because of its friendliness, but its disposition grows rougher as it grows up.

  • Moon

    This Pokémon has lived with people since times long ago. It can sense when its Trainer is in the dumps and will stick close by its Trainer’s side.

  • Ultra Sun

    As they develop, their disposition grows more violent and aggressive. Many Trainers find them too much to handle and abandon them.

  • Ultra Moon

    When it rubs the rocks on its neck against you, that’s proof of its love for you. However, the rocks are sharp, so the gesture is quite painful.

  • Sword

    This Pokémon can bond very strongly with its Trainer, but it also has a habit of biting. Raising a Rockruff for a long time can be challenging.

  • Shield

    This Pokémon intimidates opponents by striking the ground with the rocks on its neck. The moment an opponent flinches, Rockruff attacks.

Ash's Rockruff.


  • Rockruff shares the same Pokémon species with Growlithe, Lillipup, and Yamper as they are all known as the Puppy Pokémon.
  • Rockruff is the only Rock-type Pokémon that can't learn Sandstorm.
  • Rockruff is one of the two Pokémon whose evolution differs between games. It shares this trait with Cosmoem.
    • However, this is only true in Generation VII. This factor was changed in Generation VIII so that Rockruff evolve differently depending on the time of day rather than the game version.


Rockruff is based on a spitz dog (or a wolf puppy) and the extinct Japanese wolf, associated with rocks and mountains.


Rockruff is a portmanteau of rock, ruff (onomatopoeia for a dog barking), and rough (referring to the abrasive rocks around its neck).

Its Japanese name, Iwanko, is a portmanteau of 岩 (iwa, "rock") and ワンコ (wanko, "puppy").

Names in other languages

  • Chinese: 岩狗狗 means "Rock doggie".
