lime bred ones are hard and very utilitarian.
The lemon bread ones would be more heat tollerant

and might even be more apt to work

Good catch, but seriously, if anybody can find a real, hard line of Dobermans I think they'd be worth the effort. I believe there was a genius who used to be on here who took a used up, pet bred, worthless strain of tall dogs called great Danes and thru hard work and determination created one of the greatest strains of working dogs the world has ever seen, he even got famous and got to be idolized by his peers. Sure, lotsa haters be talking crap, but its only cuz they wish they half his talent.
If you just wanna be a hater that's fine but I suggests these young hog doggers forget about these old school yellows and cats, and go out on a limb. If it dont work then I stand corrected but if you make it work the possibilities could be endless...
