Pure Diamond IMO.
I'd be giving the benefit of the doubt on this one, as there's so much individual variation within Diamonds, even within a single litter to a single sire.
The rosettes, specking and nape/head markings are consistent with pure Diamond IMO.
What's the geographic origin of its bloodline :?:
What length is it?
It's a bit underweight too, I reckon. Treat for parasites, i.e. worms & mites.
