within sites like this , all you have to go on is trust , and trust im affraid seems to have lost its way , IMO , if you havent had the pleasure of seeing both parents work , but can see evidence such as plenty of pics , video footage and so on , then fair enough , but those who have nothing what so ever to back up their claims that the pups are coming from well grafting parents then i would suggest keep looking , sites like this have made it ever so easy for people to pass on their ( so called 100% from working parents) pups , trust goes a long way , but you have to go along way to find it
