Dog animation created in Maya before importing the environment into Unreal Engine. Unfortunately the rig was incompatible with Unreal so I decided to composite the Maya animation with the Unreal environment in After Effects.

The environment was modelled in Maya and textures in Substance Painter.

I also did some experimentation with Unreal particle effects adding some dust particles to the volumetric lighting.

The rig was created by Brandon Schaal and can be found here: https://brandonschaal.gumroad.com/l/Douglas
The dialogue was sampled from this video of an animation test for the film Frozen:
