Last week I reported that I had been making sure that we had most dogs’ ages as actual numbers that I could use in research. This week I started using those ages.
A few weeks ago I had done a test to see if Labrador Retrievers were statistically different on any of our survey questions compared to other purebreds. (I left mutts out of this one, because some mutts may have some lab in them, which might confuse the issue.) At the time, I realized that it’s important to compare labs to other dogs of the same size (and luckily we have size information on about half our dogs, from one of the later surveys). But then I realized that we should also compare labs to other dogs of the same age.
So today I put together a list of labs for whom I knew size and age (254 of them). And for each lab I found a matching dog of another breed that is the same size and roughly the same age. (A few people had marked their labs as “ankle height” which I thought MUST be a mistake, so I dropped those from the analysis.) What’s cool is that since we have such a huge number of dogs of other breeds to compare labs to, I can match ages very closely! Remember these ages are calculated sometimes based on birthdate. But I have a lab age 0.85 years matched to a dog age 0.86 years. 3.87 years matched to 3.88 years. And so forth. I love having this big data set to work with.
I haven’t run the tests yet – that’s my next task.
As always – answering more questions really, really helps us. I know a lot of what we talk about is the DNA analysis, but there’s lots to learn just from the survey questions. I’m so grateful to everyone who’s filled them out!

This is all so fascinating! I love that you post about it! Thank you for sharing with us!
Thanks, Kristen! I’m really glad folks are enjoying the updates. This helps incentivize me to post another one today – it’s on my list to do, anyways!
Well I do read them all. I enjoy it. I feel dumb responding to each one saying “Wow. Fascinating. Thanks for sharing!” But I do want you to know that at least one person is reading and enjoying. Lol. I’m truly fascinated with all of it!
Definitely thank you for letting me know! It’s really nice to know they’re not just going out into a void 🙂

Darwin’s Ark performs genetic sequencing for research purposes only. Submission of a DNA sample does not guarantee that that sample will be processed. For processed samples, Darwin’s Ark and Darwin’s Ark Foundation do not guarantee success in processing. Results of successfully processed samples will be made available to the submitter. You understand that each animal is an individual, and their traits are the result of the interaction of genetics and environment. Darwin’s Ark Foundation does not guarantee that the results of a genetic test will predict a trait in an animal, or in any way guarantee the mental or physical health or well-being of the animal. You agree that, the results of this sequencing will not be used for medical or behavioral purposes, or as a substitute for veterinary care or diagnosis. You understand that an animal’s ancestry and genetic sequencing results may not predict its medical or behavioral characteristics, and that such results do not necessarily specify or characterize breed or traits for the purpose of determining whether a particular animal falls under an area’s breed laws or regulations. You agree that Darwin’s Ark is not responsible for providing you with any notification about breed ancestry for an area’s breed laws or regulations. You further agree that Darwin’s Ark is not responsible for injuries occurring as a result of obtaining the swab sample. You understand that errors may occur in the genetic sequencing process, including provisioning of sampling equipment and the obtaining and shipping of genetic materials. You additionally agree that the Darwin’s Ark Foundation is not liable or otherwise responsible for any such errors. You agree that Darwin’s Ark and the Darwin’s Ark Foundation may use genetic materials you provide for research purposes without limitation.
Darwin’s Ark provides the opportunity for pet owners to expedite the sequencing of an animal’s genetics for a fee. Expedited sampling is intended for use in Darwin’s Ark research and not for medical or behavioral purposes. Darwin’s Ark and its agents will exercise due diligence to sequence genetic samples received through this for-fee program. If DNA extraction and/or processing fails, Darwin’s Ark will provide a second kit without fee. If genetic extraction and/or processing from the second kit fails, Darwin’s Ark will provide a refund less the costs of shipping and handling. If a genetic sample from the same animal is sent subsequent to failure of extraction and/or processing from the second kit without prior approval from the researchers, it will not be processed and any fee associated with such subsequent genetic sampling will not be returned. Damages or liability, including shipping and handling costs, for any errors related to the sequence analysis, including ancestry testing, of for-fee samples is limited to the payment received.

Are you sure want to change the primary account owner to another member?
We generally prefer that you not go back to edit answers... we really want your first reactions to the questions. Don't worry if they are not perfect – your first response is what is of great value to us.
However, if you feel there has been a clear and substantial mistake that needs to be revised, we can reopen a survey.
If a survey is reopened, your existing answers will remain in place. The survey will, however, be removed from your "Completed" and returned to the "Up Next" list.
To revise your answers, select the survey, then click "Retake"
You will be brought to the first question of that survey. Use the Next/Previous arrows in the lower right to move back to the question(s) you need to revise.
Once your new answers have been entered, click the "Submit" button to resubmit the survey.
Are you sure you want to reopen the requested survey?Yes, Let's Try Again No, Leave It Be
