Well, I see the puppy is registered with the ACA. Which, I won't lie, I know ABSOLUTELY NOTHING ABOUT.
I'm not sure if they go by the same international breed standards the AKC goes by or not. To be honest, I tried to find the ACA website to do a little investigating myself, and was unable to locate it. If anyone has their link, please, let me know. I guess I went with the safest, most recognized registry. I don't care who you are, if you know purebreds... you've heard of the AKC.
And... yes, the "chocolate" or "red" puppies are generally less healthy and they are considered to be a "mutation". The coloring is not a "desirable trait".
