Line breeding

[lurcher330 2,301]

Has anyone had any problems line breeding ,eg deformities or dogs that just dont seem right in the head.

 

and is line breeding the cause of some of the biggest problems KC dogs

[northern lad 2,292]

Its more inbreeding thats caused most problems with the KC dogs,Im sure that since that documentary about genetic faults within certain breeds the kennel club refuse to register mother/son father/daughter bred pups,line breeding is usually more distant relatives ie cousin/cousin uncle/niece etc

but when people try to keep a line more or less pure alot of the time they will be double up on the line,I have not seen any problems with closely bred dogs so just curious

Breeding closely wont produce characteristics that sire/dam dont carry,however some characteristics carried by sire/dam wont manifest until they show up through close breeding.Continual generations of inbreeding can lead to reduced fertility,size,vigour etc

don't worry about line breeding working terrier unless your willing to give it 20 years and the rest, show dogs you only need about 5 years...you don't get a lot of faults when breeding from tested stock as working sorts out the wheat from the chaff

[northern lad 2,292]

Surely the same laws of genetics apply as much to a tested working patt/border/lakie as they do a bichon/poodle etc,if a particularly good dog is used over many bitches you could be breeding a lot closer than realised,just to play devils advocate at least with a kc dog you can see on paper at least 5 gens back accuratley how many of the lads on here could without question do that with there new pup? I know there will be lads who can reel off their dogs origins easily,but I bet theres a lot who cant

I would say its very important to start with the right base stock or anything you produce that has a fault will only keep doubling up each line you breed,not only do you make the good points better but any shortfalls within the line will also be doubled up,genetic mutations like cleft pallatte,etc can be carried by one side without showing in the pups but 50% carried on both sides will breed some pups with it,there is more to breeding quality pups than just worker/worker,atb,WM

As WC said thorough knowledge of your foundation stock is essential,incidentally I have only bred one litter,and was advised by the breeder of my bitch to put her back to her father,at the time there was relatively few blue staffs about,the resultant litter of 7 pups were all healthy,would I advise others to do this?absolutley not,in my ignorance I could have created/passed on a world of misery to the pups/owners .Fortunatley the pups (theyre 4 years old now)I still have contact with are healthy,well balanced dogs,but this is more by luck than judgement ATB Dave

my mate has a lurcher whos out of a father daughter mateing hes as good a dog ive seen but does stupid stuff at times

[lurcher330 2,301]

What about the immune system ,I noticed when my yard had a dose of Kennel cough that the purer bred dogs took a bit longer to get over it

[the_stig 6,614]

in breeding will bring out any faults if any a few generations earlier than line breeding ...

I've a strong young bitch hear thats line bred. But I've noticed she seems to get things quicker than usual, silly things really but her kennel mate has none of these problems. I've put it down to being closely bred. But like Glyn has already said " working will sort the wheat from the chaff"!

[northern lad 2,292]

personally if owned your bitch and was thinking of breeding her I wouldnt breed to closely,given that she may be hindered by genetic weakness,find a good dog of the same type but from known ancestory,unrelated to yours.Either that or a total outcross to a dog of different breed to introduce some hybrid vigour into a strain of your own,hope some of this has been some use to you,good luck with your choice,let us know how you get on ATB Dave

i recently bred my jack russell bitch to its full brother, she had four pups one came out blue this has come from some were? i know quite a bit on the breeding of my jacks there dams sires ext and there are no blues any were but this litter i bred, the pups are now 5 weeks and the blue pup did not make it past 1 week this might be just one of those things? the 3 remaing pups are massive strong healthy things now real good pups in my opinion and am pleased i bred them this way ive kept a bitch pup back my self

you are right to an extent,but the nature of working dogs is that they must be genetically healthy to do their job properly wheras showdogs are bred to have a particular shape,looks etc. which may or not be genetically healthy for the dog.
