breeding

[mantha 2]

my mate has a dog and a bitch out of the same parents but they are not litter mates he asked if it would be ok to breed from these two dogs but i very little experiance in breeding and didnt like to say so i thought id ask on here. most gratfull for any info thanks.

too close for me i know i wont at all but ill leave it to others with more experiance than me to give there advise

thats playing with genetics - line breeding or inbreeding.. depends on how much you know what you're doing!! you can either ruin the next litter or have superb pups!

 

is he wanting to expound on some traits? or remove certain faults?

thats tricky business and not something to fool around with just for the hell of breeding.

If they have exactly the same parents then they might as well be littermates the result on paper is exacty the same, its a brother to sister mating and thats way too close

There has been some successful inbreeding’s, father to daughter, sister to brother, however these have usually been carried out be very experienced, breeder’s who have researched the genetics, and are looking to breed a particular trait’s back into the line.

too close you could get all bad genes from such a mating and the chance of heart defects and giant pups.

Is there any statistical proof that 1 inbreeding could cause heart defects ?....the myths surrounding inbreeding are never based on fact....whenever people talk of inbreeding in dogs they compare it to inbreeding in humans...and its so unrealistic its just not worth comparing.....ive seen dogs bred for generations from close families that are very inbred with no physical problems....the important part is being extremely selective on the individuals you breed from.....a father daughter,even a brother sister mating from scatterbred or crossed dogs is inbreeding yes,but is nowhere near as tight as a loose line breeding from tightly bred family dogs....there are just too many variations within the genes to be sure they will repeat on each other with any consistency.....to get heart defects or any other physical abnormalities from a one off inbreeding is highly unlikely and extremely unlucky.

Im talking from experience out of two litters i bred myself and a few others that i saw off siblings over a period of a few years they were always the worst matings some even having head problems hyperactivity etc but the odd giant pup was normal only had the heart thing once in one litter i bred they all had heart murmours so that could have been just bad luck be interesting to hear what happened to others with the same matings the sire had a few pups and that was the only bad litter he threw.

I wasnt prepared to go that close again seen some good farther daughter mother son matings and half brother half sister

and going that way wouldnt bother me but full brother sister never again

The proof is the science, in KC Staffords we are lucky to be able to test against some problems, the AHT (animal health trust) with donations and the help of the KC have developed tests for HC and L2 HGA, this means at a cost we can test breeding stock to make sure future generations do not suffer from these conditions.

 

When people breed blindly people do not know if they are breeding carrier to carrier, carrier to clear, clear to clear, affected may only show itself after a certain age! recessives genes are difficult to predict unless tested against or the lines of the dog and bitch are known in-depth.

 

Only goes to reason that breeding siblings or close relations when history is not known does increase the risk of a doubling up affected or carrier genes to the next generation.

 

I suppose the answer to this is know the lines and breeding's for sure.

The difference in proof for a working dog and a pet dog is very different.....all these tests are great for a pet dog and if i was in the market for a pet stafford i would definately have peace of mind having ticks in the correct boxes....but for a working dog....genetic defects will show themself with no need for all these lab tests....if a dog cannot perform for health reasons he will not make it as a worker hence not be bred from.....when breeding working type dogs the selection process is made on healthy vigorous animals yes,but being good at their job is the most important....a dog cannot be good at his job if he has genetic faults or defects....survival of the fittest if you like...and this way of breeding never did animals any harm for the hundreds of years before lab tests came along.....some people like to be futuristic when it comes to breeding quality dogs,but history has proved that no better breeder is there than one with a keen and experienced eye with knowldge and understanding of his subject....of which you wont find in any lab.
