There is a product called "Show Gro " that you can buy in the US, can't get it here in Canada. I have a friend in Cali that swears by it, she started feeding it to her pup when he was quite young. By 13 months his coat was on the floor. I'm sure a lot has to do with genetics though.
I know once the hair is long enough that wrapping really seems to speed up the growth.
My 2 seem to have totally different rates of hair growth, my boys hair grows really fast and my girls is very slow ( she has the nicer silk though) |
