Illustration on how to use a muffin tin to dry your samples. On the left shows how to organize the cups and write important identifiers for each sample. On the right illustrates putting the samples into individual bags after they have dried.

Our Paw Print Genetics (PPG) clients frequently share with us some of the great ideas they utilize to help in their quest to produce happy and healthy litters. Recently, one of our wonderful clients (for this blog, I will call her Carol) gave me an awesome tip regarding her method for drying out umbilical cords, docked tails, or dew claws that she intends to send to PPG as samples for DNA extraction and genetic testing.

Carol’s method involves pulling out her old trusty muffin tin and using the paper liners typically used for baking. Carol prepares one paper liner for each puppy by writing the specific puppy’s name (most commonly corresponding to the puppy’s collar color)  as well as the Paw Print Genetics ID number that is generated on the PPG website when a dog is added to an account.  She then places each liner into one of the metal cups in the muffin tin.

As her veterinarian collects each sample, Carol carefully deposits each sample into the labeled liner corresponding to the correct puppy. To prevent DNA contamination between puppies, she requests that the veterinarian clean the tools and change gloves before collecting the sample on the next pup ...

Tips on Collecting a Swab Sample

Tips on Collecting a Swab Sample

Tips on Collecting a Swab Sample Cheek swabs are the easiest, least invasive means of collecting cells containing genetic material from your dog (see this post). It’s a simple process that we cover in the instructions sent with your kit, but here’s a little more information. As always, if you have any questions, please don’t hesitate to contact us at askus@pawprintgenetics.com or 855-202-4889. After reviewing the form that came with your kit, you’re ready to start the collection process. It’s best not to take samples from a puppy that hasn’t been weaned because some of the mother’s DNA can be present due to nursing, which can contaminate the sample. Also, it’s best to wait for at least an hour after the dog eats before attempting to swab; excess saliva and food particles can compromise testing and reduce the quality of a sample. Each swab in the kit comes in a hard-plastic tube. This is to protect the sample during shipping and to minimize contamination. Do not discard the tubes after removing the swab. As you use each swab, put the tube aside in a clean place where it’s unlikely to come into contact with pollutants, especially another dog’s ...

Why use a cheek swab?

Why use a cheek swab?

The code to genetic health is found in DNA, which can be extracted from several sources – including skin and blood cells. At Paw Print GeneticsTM, we choose to use cells gathered from inside the cheek to check for genetic mutations in your dog’s genes. We do this for several reasons: It’s non-invasive: Unlike extracting cells from other sources, a cheek swab does not cause your dog discomfort, stress or put them at risk for infection. Rubbing the small sample-collection brush along the inside of a dog’s cheek to collect the cells is the least invasive and easiest method of collection for both you and your dog. No vet visit required: Cheek swabs allow you to collect a sample without leaving home, further reducing stress on your dog and making the process as simple as possible. By eliminating a visit to the veterinarian, the sample can be collected as your schedule allows, while also reducing your out-of-pocket costs. Plenty of DNA: Cheek cells also provide plenty of DNA for our geneticists to work with; DNA, the genetic material, is found in every cell collected from a cheek specimen, but not blood, as only white blood cells contain DNA. It’s ...
