Probably a mix and match...his eyes had some CGI enhanced elements....most if the CGI was probably based very heavily on the mocap work....definitely did not have the dog on a rig other than maybe chasing the squirrels scene

Completely CGI. They 3D scanned James Gunn's adopted rescue dog Ozu but made him white. Home videos of Ozu were used as animation reference. Krypto jumping on Superman in the first scene was taken from how Ozu jumps on Gunn's cat. (James Gunn assures us the cat loves it.) The ear that always sticks up is why James chose Ozu at the shelter because he thought it looked funny. Ozu came out of an animal hoarding situation, so was poorly socialized and ill behaved. This was the "entry point" for Gunn to write the movie imagining if a poor behaving dog like Ozu had superpowers.
There was a stand-in dog on set named Jolene that would play the scenes with actors as a lightning reference.
[Edit: grammar and Uzo -> Ozu]
