: ...thanks for not pulling my password!!
: I don't think you got exactly what i meant this is a very interesting but hard
: subject to discuss in English, but i guess my English is better than your Swedish!?
: All i'm trying to say is with inbreeding theres risk involved and a possible
: disaster overdone, and i don't talk about a single breeder using this method now and
: then, but if ALL are doing it ALL the time over a long period of time.
: Even if one perfect stud is over used you could get in trouble when the second
: generation is born, theres an example of that about a bull called Matador who
: carried a ressesive defect for one testicle, first gen. no problems and the
: offspring were as healthy as there father but with the generation, inbreeding half
: brother to half sister, the ressesive gene now doubled popped up resulting in
: infertility.
: If a closed population (like the JDJ bulldog) is to stay healthy for an unlimited
: period of time the active population needs to be 500 or else they rapidly start to
: lose there genetic diversity and you need to add fresh blood.
: It is impossible to weed out all defect genes, the average living being carries
: about 5-10 genetic defects programmed into there dna.When i mentioned foundation dog
: i in my post was generally speaking of FCI approved breeds.
: I believe there problems comes from show breeding for a sertain look using
: inbreeding to get it.
: I would not recommend it to start with, it is in my opinion for the experienced
: breeder, i don't do it my self.
: Would you recommend this breeding practice to a new breeder having his first or
: second litter??
:
: I hope i don't sound like an ass, remember this is not my nr. one language!!

: Weed out the defects from gene pool and I don't think it was a small gene pool with
: "12 to 14" different dogs(thats not a small gene pool) thats for sure! The
: people who cull and take the risk I believe will see results and make the
: difference, The real test is "what are you producing?" Everyone already
: knows what we get when we do noting! Personally I have seen Great results going
: tighter then set your tight stock into something looser. Paul C. has a full brother
: to sister b###h of mone she will be bred to Bo watch what that breeding produces!
: Now that b###h is as muscled up and near perfect conformation as one could ask for.
: When I need an out cross it will be a very tightly bred Old Southern White who has
: great health ,temperment ,structure but tight also. Remember we are not going from
: one foundation dog but two dozen different dogs.
: Where do you get "the" foundation dog? Not looking for anyone to agree by
: the way , I usually keep my thoughts on breeding to myself as I will not argue and
: enjoy just doing my own thing. I jumped in because I happen to like Bryan and his
: desire to make good positive changes ,can we agree the breed is a mess? what would
: you do to change that?
: You or anyone does not have to agree I won't pull your password.LOL! Everyone sees
: things differently. Take Care Bud: Mark @ Big Sky

: I don't agree with Mark, the gene pool was small, yes inbred dogs breeds
: consistently
: but they also double up on defect genes, and a population under 300 will start to
: lose genes resulting in depression, early signs are lower fertility, weaker immune
: system, smaller dogs and shorter lifespan.
: Most breeds recognized by FCI is a result of inbreeding but they are not the
: healthiest dogs around, they all have ONE major defect from the foundation dog that
: breeders then have problem avoiding.If conformation consistency is your main
: objective keep inbreeding everyone, personally i don't think these dogs need more
: uniform and over all health is my main concern.
: Don,t get me wrong i don,t want other breeds/lines crossed into our Johnsons but i
: think a widening of GOOD dogs used wouldn't hurt.

: PS there should say LOWER not HIGHER in my previous post .
