Is there a way to upload a profile video?

I was able to upload a few. Though not all the videos I sent went through. This is as of June 20,2015

Although I don't know if what you asked can be done, another way to accomplish this would be to include activities with your dogs and your Rover dogs, (ensure you submit 5+ photos per stay), and make the Rover Reel public and check the box to add it to your sitter profile.
