Greetings
Ginger, welcome to the Forum !
Yea, our little ones do grow hair like mad, and "IF" you want your little guy to have a long coat, you need to maintain it, however...
I do things with my guys which is relative rough and tumble compared to most here, and get them to the Groomer (about 3x yr) for a short trim. We go hunting and they get wet and muddy frequently. I'm more interested in the abilities of the Breed, than their appearance.
As far as the eye problem...
You probably should keep the Hair trimmed back until you can do a visit to the Vet. Sounds like that should be ASAP.
Vocalizations are just a start...
with what will no doubt be an amazing experience with the Yorkshire. I've frequently used terms like special, individual, clairvoyant, institutive and unique, when it comes to their personalities.
Having a Yorkie is more than just an association, it's an ADVENTURE !
Welcome again !
