Abrother and a sister argue over who gets to name their dog. what type of conflict is this?

This is an example of an external, man v. man conflict.

The conflict is external because everyone involved in the conflict knows what’s going on and there isn’t an internal debate within the broker or sister. They are simply outwardly arguing over the appropriate name for their dog. Because the conflict involves two people, it is man v. man.

I hope this helps! :)
