EBV’s Estimated Breeding Values
EBV is an effec ve way of reducing the risk of passing hip dysplasia onto the pups
produced during a breeding.
This tool uses all screening data and pedigree informa on from the individual dog and its
surrounding family to more effec vely assess the gene c risk that each dog will pass to its
pups, and it is more accurate than relying on an individual dog’s test score alone.
A posi ve EBV gives an elevated risk of the dog passing on hip dysplasia to its offspring
irrespec ve of its own hip score results.
A nega ve EBV gives a lower risk of passing on hip dysplasia to its offspring.
The average EBV of the dogs tested was -12.8, with the highest being 19 and the lowest 63.
The EBV of a dog can change over me as this is based on the tests of family members as
well so the more dogs within a line tested the more accurate it becomes.
This can be found on the Kennel Club’s website.
The EBV of a li er can be worked out by adding both parents scores together and dividing
them by 2.
Recommenda ons
1)
When choosing a sire or dam to use, those with lower-than-average hip
scores AND EBV below zero can reduce the risk of passing hip dysplasia to
the offspring.
2)
EBV should be considered as part of the whole picture when breeding and
should not be used as the sole reason to breed or not to breed.
