I'm trying to add a few of my own textures into Doggy Talents, but I'm having difficulties. I have tried opening the mod and adding my textures to the assets file, with the correct naming. I've also tried using the file structure of the "Doggy Talents TP" texturepack to add my skins, but they didn't show in game that way either.

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!
