i cants use the next doggy talents for forge 1.20.1 cuz it has a dependency for doggy talents even tho it dont say any on the download page and dt dont have any 1.20.1 version.... so how do i even use this ?

I dont know where you even got that information from, DTN is completely seperate from DT and definitely can and must be used without DT.

game says deff not, evrytime i install it is crashes an says needs required dt

Please see FAQ in this section. Thank you.
