Is this a healthy Shar pei?

Im hoping this is the right place to ask, I came across someone I know through a friends Instagram accounts posts about their dogs, is this a healthy looking dog? I'm not too clued up on Shar Peis and I know all dogs are different but idk his dogs looks odd and I'm just concerned about their well being, he also had videos where he had two locked in 1 cage and it just seems odd , I don't wanna be a hater I just wanna know if they're okay
