Many animals/dogs are not amenable *at all* to being confined to small/tight spaces. None of my dogs would tolerate crates, and I honestly couldn't blame them one bit. Instead, we used the Iris Pen and had it next to our bed when they were puppies.
Keep in mind that these tiny creatures, as puppies, were previously used to being with their Momma and litter-mates 24hrs a day - cuddled in close, nice and warm with all that company. Then suddenly, someone adopts them and they're put alone inside a small enclosed "box" - expected to just 'flip a switch' and be okay with it....it doesn't really work like that with little baby creatures who were previously 100% surrounded by their furry family and now 100% alone.
On top of that, 8 weeks is really considered premature to be adopted out for a yorkie; he should've been kept with his Momma until a full 12 weeks old....so this is unfortunate as he will now miss out on some of his socialization skills that are learned from Momma and litter mates.
Additionally --- you should be aware that at 8 weeks old, he is *much* more vulnerable in terms of hypoglycemia, health overall, size, etcetera -- so keep a vigilant eye on him - and make SURE he is eating a meal about 4x per day!!!
