Slight chance for pillagers to spawn with a pet "Hound" (wolf) that will fight alongside them! Or a pet parrot that follows them! So watchout and be cautious!
Wolf spawn chances and parrot spawn chances can be adjusted with the following commands
Wolf:
/scoreboard players set wolf_chance oszu_pf xx
Parrot:
/scoreboard players set parrot_chance oszu_pf xx
With the chances being out of 100, for example 25 wolf chance, 25 parrot, and the remaining 75 will be none, the default is 20 wolf, and 5 parrot

If you would like me to port this to any other Minecraft version, i would be more than happy to do so, please contact me! my details are below.
If you do find any issues/have any recommendations, suggestions for optimizations, improvements, or new features to add, feel free to contact me!
wolf chances are calculated first, and the parrot chances are added onto this range, so if wolf chance is 90, and parrot chance is 20, the wolf will spawn with a roll of 1..90 and the parrot will spawn with 91..110, but the roll only goes from 1..100, effectively making the parrot chance in this case only function as a value of 10
