coat length and color

(please move this topic,if it's in da wrong place)

I have a 9mth old lhasa apso .I just wanted to ask other lhasa owners and others who know,that how long was their dogs length when they were around the same age?
And when I got my dog at the age of 1.5 mths,he was pure black,just his feet and his chest were white.Now his back,face tail etc have plenty of white hair and his face has brown hair too..anything unusual happening?(although it doesnt matter at all)

I'm not very knowledable about Llasa's but I do know that their coat colouring changes and shrinks as they age.

It happens with GSD as well. Its just them maturing

Coat length also depends on whether or not you are showing your Llasa..

if you are showing it, then it should be floor length.

If not, you can shave them
