markings

He is a black and tan with black mask and brindle.    E^M- a^t- k^br-  Very cool!  May I add him to the photo gallery?  

Sure you can;) thank you ;)

Do you think these colours can come out of crossing gsd with Labrador?  As that's what I've been told he is and everything matches but some people say these breeds don't carry brindle gene? 

These type markings aren't common but they are present in labradores, so when crossed with a breed that isn't dominant black they can "pop out".   Check out this page http://www.blueknightlabs.com/content/v…

 How would you like photo credit for your photos to read?
