The Butters blood is effectively gone. We've been working within the existing family but I have three other people who breed based on my breeding but do their own thing with crosses. I trust them absolutely when it comes to judgement of a working dog and we get together once a year to look at what's been going on. (One bloke lives 15 hours from me so that's why it's only once a year.) They try other dogs or variations on mine and occassionally breed so our get together involves a few beers, a few barbecues and a few pig hunts to test things out. I have one of my mates dogs here now, Geoff. He's by a dog produced from an Ian Colley dog over one of my bitches (Gina...Russell x Kelly). That dog went back over Kelly to produce Geoff.
He's a big, rough dog of about 12 months. Can find them, will tackle a rough pig without hesitation and let go on command. But he is bloody ignorant, not as easy to fine tune as mine but well worth the experiment.
