Hi!
Welcome!
I'm still trying to figure out all the coats too. The best thing I can tell you is that at these ages they have their puppy coats and it could all change by the time they are adults. The best indicator would be what type of coats do their parents have. It's all part of what I find so fascinating about this breed. Their coats change, the color changes, they all look so unique when finished. Gracie Ruth's coat is quite cottony right now, it mats very easily. But both her parents have good coats so I'm hopeful that she will too. You may find it easier to keep your girl clip short for right now. I clipped Gracie this summer and our grooming time became much more enjoyable. Boo seems to have a combo of types. His body is more wiry but his head and legs are silky. We keep him clipped in the summer to help keep him cool because I'm sure there is a Yak somewhere in his family tree.
I believe Annie is what's called a Red Leg Yorkie - I'm just learning more about them. Her coat was silky, but only her body hair grew. I never had to trim her legs, head or ear hairs. They never grew.
A good shampoo and conditioner will help. Detangler if needed is also a good thing to use. And a good quality food will be the best thing to help their hair grow healthy and strong. Check the Health & Diet and the Grooming forums you can get a lot of good info there.
What are your babies names? Oh, and post some pictures as soon as you can!
