A quick report from a Darwin’s Ark researcher!
I’m still working on different ways of using our survey data to evaluate whether different breeds really do have different personalities. (I’m a dog person so I do believe they do – my boss is a cat person and argues it’s all in our minds.)
The latest is this new statistical technique I just discovered called Latent Class Analysis. Basically what it does is look through all the survey answers, and tell me if there are groups of dogs who tend to answer in particular ways – so, different “classes” of dogs. Our hope is that this will correspond to breeds or breed types, but we’ll see. I’m deep in getting this software to work right now.
Today’s goal is just to find out how many classes of dogs we see in our data – two? Five? Ten? Only after figuring that out can I see which dogs fall into which class, and then see what the similarities of dogs in the same class are. (I’m guessing size and age will be really important in determining class.)
Thanks SO MUCH to all of you who have filled out all the survey questions! It’s amazingly helpful to have lots and lots of data to play with here and for that I owe all of you.

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.
