3½ month puppy, just pees everywhere even though we’ve potty trained and poops outside. Where our 1+ years old dog goes to poop and pee

Puppy pees when excited, squatting, standing, lying, sitting THE WORKS THE WATER WORKS! Even after emptying her tank there's always more! In terms of pooping Oh! She'll beeline for the balcony (the designated drop zone). We've tried the quick shuffle the puppy out when they try to pee (no avail), show we are angry [not yelling or scaring](no avail) and don't let them in till she's done (NO AVAIL!).

The fact that she listens her name, avoids accidental poop drop and accidental play bite (she is still land shark stage), somehow likes drinking her own pee (not her sisters) .Loves play fight with her sister 1+ year

What is going on with her? Is it something about her training or something else?!
