In Catch and Tame , the dog is tamed by using the right animal-capture item on it; the wiki says the Dog can be tamed with a Basic Lasso or higher. One recent Roblox guide also describes a similar pattern for other animals: equip the capture tool, find the animal, use it to tame, then unlock the related item afterward.

What to do

  • Get a Basic Lasso or better.
  • Find the dog on the map.
  • Use the lasso on the dog until it is tamed.
  • If your game version requires it, check whether you need a saddle or follow-up item after taming.

Note

Your wording looks a little mixed with “build ur butterfly roblo c,” so I’m interpreting this as a Roblox pet-taming question rather than the Butterfly Simulator page itself. If you mean a different Roblox game, the exact taming method may change.

TL;DR: use a Basic Lasso or higher on the dog to tame it in Catch and Tame.
