CUTE PICTURES !! and ok - I'll try - I'm no expert but based on my 2 who are one of each - and from what I've read and talked about for 5 years now
1st What do you think they are?
Silky and PUPPY LOL (hard to tell at this age)
2nd- Can you be a Silky on the outer coat and cotton on the underneath?
I don't know but there IS something called Modified Silk - which is in between the 2 types
3rd-Do silks grow slower?
I think so yes. Chanels hair grows 4 times faster than Cheri's whp is silky
4th- I cannot get Bellas hair on her back to grow even and get that long....I get her groomed but say only trim her hair on her legs and shve her feet and do nothing to the hair on her back, it that what I am supposed to do or should I have back hair trimmed also to promote growth?
I don't think cutting the hair promotes growth - at least not in my own experience with my girls - I'd just let it grow and not cut it unless you're just doing it to even her up
5th- Someone said Diggy looks soft by his coloring? are there coloring patterns for certain coats?
good question - I've seen dark coated silky coats and dark coated soft - True silk will have a blue sheen to it & feel cool to the touch
How many coats are there and can I see examples of them?
I really think 3 types are seen the most - Silk - Modified Silk and Soft but the experts can tell you better
So you can see a Puppy who will grow into a soft coat - here's Baby Chanel who already showed signs of BIG Texas Hair LOL
