Bloodlines that improve an attribute - Page 1

How would you be able to find a bloodline or a dog that improves a breeding for example health, colour pigmentation and body structure.

You would have to find a breeder that actually has developed a bloodline and selected for certain traits and found breeding partners with dominant genes with those traits. You can say all dogs have a bloodline, but not all dogs come from a bloodline where the dogs in the bloodline have been selected for specific traits or the progeny have been followed up with to see what was produced, which is the only way to know what genes for specific traits are likely to be dominant.There are not that many people who breed like that. It takes generations and knowing the dogs back many generations to be able to make more accurate predictions of what a breeding will produce. For example, Jinopo has been breeding for decades based on a sire line approach and probably has one of the best databases on what their breeding stocks' genetics are. Having said that, I don't know that I would buy a dog from them.

Changing an attitude is one thing but changing a temperament is quite another; so are you talking attitude or temperament??

select a dog that carries desired traits, and look at his parents and siblings and possible offspring, easy as that

thanks for replies, i wouldn't really buy from jinopo either seems like it is easier than i thought. @nans god I'm talking about the physical attributes of a dog for example one breeder may breed specifically to make a healthy dog that can live for 14 years and still be healthy.

The problem with the longevity thing is you don't know if longevity is genetic in a dog until he dies from an older than average lifespan. You can look back at a dog's close up ancestor's for longevity and if that dog has traits you are looking for, it is a bonus.

OH OK so we're talking conformation attributes, hard to determine and predict.

You are maybe not going to find it all that difficult. Go where the breeding is - if you want conformation points, like depth of pigment, correct size & strength of bone, good gait, etc, then Showline people, in Europe at least (you don't say where you are, or how far you are willing to look) will be actively breeding for those things. If you were not so bothered about the visual stuff and wanted to concentrate on e.g. potential training aptitude, then look at working lines primarily. But do what Duke suggests - tour local breeders, and attend Clubs, Shows, whatever - where there are a few different dogs; look at a few dogs, pick one that seems to fit what you want, then study it; and its ancestors; and its siblings; and its offspring for what is known so far, as much as you can. ASK the breeder(s) a lot of questions. Take your time to observe. When you start to ask and find out, things like the longevity rates and health issues and how colour carries through, tend to emerge. It isn't a race, or a "walk up & pick one off the shelf" type of thing ! And always remember: its a crap shoot, sometimes you get luckier than other times - the genetics are too complex to give anyone absolute guarantees.

its easy Hund, I wanted black pups, so I bred a black male to a black female and got lucky...............all pups are black LOL

Most Black pups have depth of pigment, Duke .   Maybe the OP wants Black & Red though; lots of variation possible there !
