So she has AKC purebreds but then does have mixed litters from time to time?
No, I didn't want to stir the pot at all, just wondering why everyone was being so supportive here yet in other cases the poster seems to get a bunch of worried replies about the fact they are buying from a BYB.
I for one LOVE "shorkies" and "labradoodles" haha... so I understand wanting a mix and for them to be desirable

Just wondering was all.
I think in this case, go for it. You already have a pup from her and your son knows what he wants!
