Issues exporting animation to FBX in Blender 2.90

I am pretty new to blender and so I started off simple with this wolf animation. The problem occurs when I try to export to FBX. I have been searching the internet for a day or so now but no solutions have worked. My weights are all 1.0 for each bone and I have followed the export methods of countless forums.

My biggest clue for my problem is when I go into edit mode.

As you can see, my mesh (and also rig) is very tiny compared to the object mode. I am at a loss for how to fix this though. My limited experience with this and UE4 tell me it is some small setting I am glossing over. Any insights would be amazing, thanks!
