No it can’t be transferred to dogs, nor to humans.
It is an immune disorder in which the dog’s immune system recognises the dig’s own muscles tissue as foreign and attacks it. Some dogs may be genetically predisposed to immune-mediated diseases and this disease gets triggered by something. Most of the time the trigger is not found. The dog you sent the pictures too had wasted quite of his masticatori muscles, is he still able to eat ? Is he comfortable ? Agressive treatment with steroids help things settle and should make him feel more comfortable. I am not sure if he is on any other medications hence I have suggested to see your vet.
