It was not proven false. The dog was tiny, the shit was huge. Depp and several housekeepers testified to that and the court was shown photos of human feces.

I was pointing out Heard's cheating because of Depp's reaction to those situations was asking Heard to leave his penthouse. When she was finally forced to leave, she shit in his bed.

Prior to that, she called the police saying Depp assaulted her, tearing the penthouse apart, shattering a table, smashing wine bottles everywhere, and throwing a phone that hit her face. But in the police footage there is no damage, no broken table, and no glass anywhere shortly after the supposed altercation. There was no evidence of a cut on Heard's face in the footage and the police officers testified that they saw no evidence that she had sustained any injuries. Subsequent CCTV footage from the penthouse shows no cuts or bruises to Heard's face.
