Hi and WELCOME to YT
! Yorkie puppies will change a lot over the first year, though they tend to reach their adult weight around 6 months. If the mother has a long snout, there is a good chance the pups will too. But honestly, it can be hard to tell. Are you looking for the shorter snout? If so, I'd definitely hold out for that specific characteristic if that's what you're in love with bc some yorkies really do have that longer snout appearance. My Marcel (in my avatar) has a short snout - and you can see in his picture what he looked like as a puppy...it looked short as a puppy too.
