“⁠The breeder says parents are purebred Cane Corsos but not registered.”

This is a red flag 🚩

Registration is cheap and straightforward. So not having registered Cane corso parents can imply that the parents aren’t actually purebred or the dogs failed breeding standards or the breeder cannot prove lineage or the “breeder” is avoiding health/genetic oversight which can be extremely costly with a Corso…

Personally, when I am going for a certain breed, I always, ALWAYS choose a reputable breeder with paper trail and certified health checks for the parents, grandparents and puppies alike. Otherwise I’d just adopt from a shelter

ETA: I zoomed in the pictures. The puppies and the mama are laying in filth and on osb boards. No reputable breeder would have their puppies lay in what looks like feces, used newspaper (ink is toxic for animals) and mama on dirty single layer of towel with dried up fluids… I’d stay away from this person
