So, I have this expression from Portuguese that says that "A dog with two owners dies of hunger"
It has the main objective of expressing that if you assign more than one person to take care of something (usually a problem), they'll all think that the other one will take care of it and end up doing nothing.
Is there anything similar in English? I thought about "Too many cooks spoil the broth" but it doesn't have the same intrinsic message - this one comes across to me that if you have too many people taking care of the same thing, there will be too much done and in the end it will get bad from EXCESS of action, while the Portuguese saying has the underlying meaning of neglect.
