I had a really good dog put him over three different bitches all line bred . All ended up shite . Put him to a scatter bred bitch as a favour for a friend produce a decent litter . Then he accidently shagged his sister and produce two world beaters . So who knows that's the highs and lows of the terrier world . It can make or brake you . It's a hard game but when it comes right it's the best game . Don't let your head drop . Just try again with different dog . All I will say is if you do try her again treat it like its her first litter and don't let the real first litter make you have rash dec
