So sorry about your sweet boy. They never can be replaced and it is so hard. It's never long enough.
Have you decided on a litter yet?
I just lost my girl at 9.5 to hemangio and it was devastating, so I too, have spent a lot of time researching pedigrees, health, longevity, COI, etc.
I personally would steer clear of a line with lymphoma. Cancer is huge in goldens and there's still a lot of research that needs to be done. There doesn't seem to be anything conclusive about hemangio being genetic, but there is evidence that lymphoma is. Cancer is really hard to avoid in goldens and ultimately, they won't live forever, so I do feel like it is different if a dog passes away from cancer at 14.5 vs. 7.
There is a lot of research on the COI-also not a tell tale predictor of longevity, but it helps. Lower is typically better. I like to see a combination of relatively low COI with proven longevity. It's up to the owners to update k9data so it's not foolproof but I like to see the cause of death, especially when they're young. I steered clear of pedigrees where the causes weren't entered. Sadly, just because the parents are all 14 plus, doesn't meant that the puppy will also be that old, but it certainly gave me more peace of mind.
Willie, the sire in the first litter you listed, shares some of the same lines as my girl. She was a wonderful, sweet, smart, beautiful dog and the puppy that I've selected for myself also shares some of the same lines. I was really pleased when I discovered that! My hesitation there is lymphoma.
Thank you and I am very sorry for the loss of your girl to Hemangio. What an ugly cancer that is.
I looked at many litters and was discouraged to find cancer even if it did not show up on first glance but if I clicked into siblings of some of the dogs with great longevity I would see that one of his/her brothers or sisters died young of some form of cancer (for those on K9 that do disclose COD). I was reading an article recently that if you take any given litter there will be a % of dogs that will most likely pass young from this awful disease. Maybe there are lines out there that have been lucky enough to escape this?
Oakley was just over 8 when he passed and he was from a reputable breeder and from a litter of 9 boys. After his death I contacted the breeder only to find out that 3 of his brothers had also died from Hemangio within 6 weeks of each other. So sad
I read something also recently with regards to lymphoma and ticks / lyme disease and a possible correlation.
In the end I did go with Litter #1 and found out after I had made the decision that the dam from Litter #2 did not conceive. I know there is Lymphoma in that line and I hope knowing that does not haunt me but the litter offered so many other wonderful traits – including a low COI. We own a cottage on a lake and we get a lot of company visit us there including other dogs. It is equally important that we have a dog with a great temperament. My breeder had mentioned to me that she had seen and met Willie at various shows and that he had a wonderful temperament & disposition that really stood out to her – interesting his name is “Sweetgold Mr. Wonderful”.
Which Litter did you go with?
