Coi in golden retrievers

[DawnS]

Hoping someone more knowledgeable than I can offer advice.
I’ve been waiting on a working golden litter to be born and they are finally here. I thought I had done my homework in checking hip, elbow and eyes and meeting mum, grandma, and full sister from the same parents. However it has now been pointed out to me that the litter will have a coi of 19%, well above the breed average of 7%. Is this a deal breaker? I’m seeking a dog for agility and as a pet so they really need to be structurally and behaviourally sound.
Any advice appreciated! I’ve been looking for well over 18 months for a pup and thought I’d finally cracked it, so I’m pretty disheartened.

Coefficient of inbreeding

I am no expert on dog breeding but I would hope that provided there are no serious health issues in the known family that they should be ok, fingers crossed. I take it the hip and elbow scores are really low.
A friend of mine bought a collie pup, she checked its parents had been hip scored but didn't ask what the results were. Big mistake, the sire in particular had very high hip scores and it transpired when her bitch went lame and she was tested that hers were appalling. The sire was a successful show dog and regularly used at stud.

Thank you. Those articles suggest that it is a big problem. I'm just baffled as to why if that is the case then why the breeder, who is extremely experienced, would pursue this mating? Planning to ask my vet but i imagine their specific knowledge of this is limited, so any more insights very welcome.

Some breeders believe in line breeding which will always result in a higher COI. Its mating closely related dogs who are good examples of the breed to increase the chances the puppies will be the same. If its done right its fine.

The litter should never have COI over 25% (unless small gene pool for the breed) so whilst yours is high I wouldn't rule out the puppy based solely on this.

Can you ask the breeder for the full pedigree so you can see who is on there more than once and check their health scores?

You may find it's because there are far less working golden retrievers. My first one had some inbreeding and died at ,7 of kidney failure and always had poor skin. Our present dog the bitch was in Wales and was driven to Scotland to be bred. He is still related to our first dog!

In some breeds/types of breeds (eg working type if only bred to working type) will be numerically smaller so even the best/furthest away matings may still be higher in terms of COI than a numerically larger breed as, with some breeds and types in the end all lines may tie back up after a few generations. Wouldn’t discount a pup based on COI only unless the dog was heavily line bred back to a dog that had known health or temperament issues, or other undesirable traits.

Thank you. Looking at the pedigree, there is holway on both sides which I guess is the common factor. I will look up health tests for those I can find, but of course they don’t tell you about cancer which is my primary concern.

Do you remember what % inbreeding they had, roughly?
