UE doggytalents{v1.7.3a} [Doggy Talents] (doggytalents)

You seem to have a strange version of the Doggy Talents mod, which is in "errored" state. I haven't played it myself, but the latest version I found of it for 1.7.10 in the official thread is a file called "DoggyTalents-1.7.10-v1.9.0h-universal.jar", so having one that shows as v1.7.3a and doesn't show a .jar extension in the parentheses after it the way your other mods do is not a good sign. Where did you get that one, and did you extract it as a folder or something? (there might be a few weird exceptions, but generally it's not a good idea to extract mods as folders)

Edit: since pdcbta55 mentioned incompatibilities, I searched both the Doggy Talents thread and the Copious Dogs thread for mentions of the other mod, and Doggy Talents apparently had a fix in v1.9.0f for compatibility with Copious Dogs, so v1.7.3a could have problems with it.
