About crossbreeding :

 

It take several generations to purify once you cross breeding 2 breeds  together, and I never cross with any genuis breeder who have that breeding plans in mind before ( except using CSP for blue color), all crossbreeding that I ever  meet is just accidential  breeding or using breeding stock from garbage ills ..., as GSD and Dobie are the 2 famous western breed in Thailand at that time, you can easily see the GSD type TRD in the region where GSD are populare............

 

Crossing with GSD for working purpose or crossing with Dobie for show purpose are just BS talk for make the breed look great, it's not true in my opinion.

 

About bad color :

Don't be surprise getting bad color if breeder continue cross color breeding.......and don't be surprise getting skin problem if breeder continue breeding recessive gene....
