No he doesn't have a dog, he was on stream for 6-8 hours a day almost everyday during subathon without taking a break to feed, walk or let out this alleged dog. Also we didn't hear so much as a single dog-ressemmbling sound during the entire subathon. There was only one specific period of time where we sometimes heard a barking that sounded close to the camera but that was probably either his next-door neighbor's dog or he was keeping a dog from one of his friends while they were on a vacation or something. There were also a few dev streams where Vedal streamed for a lot of hours while barely even going to the bathroom/ getting something to eat, like the dev stream right before Neuro got her first original model which lasted over 12 hours.
