I really want to use a resource pack with Doggy Talents called Fresh Animations and i can't use either one of them because if i do use both of them, Minecraft would just crash. Fresh Animations requires optifine to run. If there's any solution to this problem, I would greatly appreciate it if you'd let me know so i can try to fix it.

Hey, thanks for taking the time to create this issue and I'm sorry I didn't get round to resolving it. I've not worked on this project for a while and have decided to archive the git repository. Fear not, there is a fork https://github.com/DashieDev/DoggyTalentsNext which might be of interest. I don't expect to be back within the Minecraft community so farewell and happy mining!
