Thanks for your professional and valuabel advices!!!
I already contacted the owner of Liser Lites Australia, he is a great person!
He gave me some suggestions, but he is a breeder/exhibitor of Afghans...
so he highly recommended me to ask expecially to Yorkshire Terrier exhibitors to know exactly how LL products work on Yorkies' coats
(in Italy I have not yet meet one thats use LL ...is incredible!)
...in this direction you are GREAT, Mardelin !!!
Your suggestion are always welcome !
