In The Last Jedi, we encounters the Fathiers at Canto Bight.
Are they Sapient beings?
The arguments I see are:
They appear to understand language and complex commands. For example, Rose says, "we need cover" and the beast may appear to understand this.
They appear to be enslaved the same as the humans
There are other clearly sapient beings who do not speak what is recognizable language to us (Wookiees) so we can't tell whether fathiers grunting has similar standing.
So exactly how intelligent are they? Do they rise to level of sapience? Is it possible they are effectively an enslaved people?
