Hi and welcome to YT
.
Many dogs (and animals) are *not* amenable to close confinement and cannot tolerate it...can't really blame them either. None of my 3 yorkies were amenable to the crate - they totally hated it and went nuts - so I don't believe in forcing it upon those kinds of animals when they react like this.
So, I wouldn't force the crate on your yorkie. Instead I'd try using an Iris Pen (walmart or amazon) or similar to create a small space for him. I always kept my yorkies in our bedroom with us bc we have to remember -- this puppy went from being around his cozy Momma and littermates 24 hrs a day to...these new humans and being put in a crate all by itself - that's quite a shock to it's normalcy.
Also, he's been taken away from his Momma 3 full weeks too early - so he may have socialization issues later. I'd be very good about socializing him properly (and safely, since he's not fully vaccinated yet) and learning what you need to do for a puppy who has been taken from Momma too early.
