I love all meat ive tasted, if its cooked properly but I cant always do it myself. I find wild rabbit has that tang I find nasty yet I lived in a house as a lad where we had rabbit 5 days a week in different ways and always delicious, and a wild rabbit casserole in a Scottish restaurant that was perfect but the chef struggled to get them locally even though the countryside crawled with them.
All joking apart when you are breeding/genetic engineering you can breed aggressive or placid or whatever you like if you know what you are doing. You could in theory go 2 ways if you had the facilities and breed a family of placid dogs and a family of aggressive all from the same couple. Its select and purify or narrow down if you like. I dont know how long it would take or cost but it could be done. I think thats why they use mice in experiments, its just cheaper.
I dont know how far you can carry it on to a conclusion in dogs and most breeders are secretive about it, or even deny it altogether. Ive heard of years of it without going out at all. Personally Im still doing it with success. You can get mutations after intensive I think like the Bent head in Bullterriers and the coat colours in intensively bred foxes but Im no expert. You could ask someone like Ken Gould if hes still about, he knows all about it and more than me.
I dont know if I'll live long enough to tell you. If you were planning on breeding a litter of Greyhounds you could go on Greyhound data and put both prospective parents in and it can tell you what the coefficient of inbreeding is before you even mated them. All Greyhounds are related.
You cant add with inbreeding but you can improve stock. You need to start with good dogs or at least one, dog or bitch. They might not be pure but they have qualities and you can breed to them in and in, culling anything that isnt healthy.
Ive put this up before but look at this pedigree to produce a stud Bull of purity. They were not afraid to go close in those days and the butter yield just went up and up.
I think you have to keep an eye open and look for bad aswell as good traits. If you get to a pre potent or pure dominant stud for instance, he could mate faulty bitches because his DD genes will cover any faults the bitch has, but that only works for one mating because you have reintroduced recessive genes back into the blood.
You are inbreeding,well done. People get all tied up about diffrent relations, brother/sister sire/daughter etc. That isnt the important thing. If they share a common genes and must be very healthy ,thats the main thing
