If you want to do short pulls like the ones in your video then YES go up on weight. Your dog is pulling that with great ease and knows what you want from him. If you are just begining I might pull a few times at that weight but your dog seems to know what you expect him to do. If you were going to do long walks that would be fine as by the end of the walk it would be more of a struggle to pull.
What does your dog weigh? What I would do, if you are doing pulls like that one then I would start the dog at your current weight. Make the dog do 2 pulls at that weight. Add a cinder block and 2 pulls, another block, 2 pulls etc until you see the dog putting out a decent but not STRAINED effort to pull the wagon. Cinder blocks usually weigh anywhere from 27-34lbs so you could try going to a used sports store and buying plate weights. They are usually pretty cheap there. I buy 5lb and 10lbs plates. You can use these plates instead of blocks and they also drag easy.
Your dog looks good, keep the dogs energy the way it is. Remeber you arent at a show, its training so dont be afraid to stop ahead of what your dog can do. My rule of thumb, when I cant see your dog, and even on my own, If I think the dog might struggle with the next weight added I stop and just do a few more pulls at the current weight.
