Used two separate quarter bred outcrosses mate so pretty diluted when I worked them .Theres a lad I know used to keep pat/bulls in varying degrees of dilution and he worked them all .Got to see them first hand and have to say you wouldn’t turn one down .If we are to believe the old books ,pics and gossip ,all the black types had bull infusion so no getting away from it really .
I was never interested in the first cross but a bit of bull never did any harm that’s for sure .
Everybody has a take on it but unless you’ve worked them words mean nothing .My old bitch I have here is 1/16 goi
