Sample cheek swabs are the easiest and least invasive means of collecting cells containing genetic material from your dog. Although it is a simple process, it is important that you fully understand how to collect a sample using a cheek swab. Follow along with us as we walk you through the swabbing process using one of our sample kits.

Each kit includes a requisition form, a return mailer, a label, and a cheek swab with a biohazard bag. After reviewing the form that came with your kit, you’re ready to start the collection process. If swabbing a puppy, it is 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. Be sure to also wait for at least an hour after the dog eats or plays with shared toys before attempting to swab; excess saliva and food particles can compromise testing and reduce the quality of a sample.

When you are ready to begin swabbing, remove the swab from its protective packaging and be careful to not let anything touch the tip of the sponge. Insert the sponge between your dog's ...

Four things to Consider Before Buying

Whether you are looking to adopt from a breeder or a shelter, it is important to thoroughly think the decision over. While we want pups to be adopted, we also want to ensure the dog is a good match for home & lifestyle

If you are thinking about adding a new addition to your family, here are a few thoughts to consider and questions to ask yourself before adopting a dog.

1. Your Living Space

Do you live in an apartment? Do you have a backyard? Does your home have a lot of stairs? These are all good questions to ask yourself as some dog breeds have different needs when it comes to living spaces. Breeds with long backs and short legs, such as Corgis, can injure themselves by ascending or descending stairs. On the other hand, high energy breeds such as Australian Shepherds, thrive by having a backyard that they can run freely in. By considering these items, you can ensure a successful fit for your home.

2. Other Family Members

Who lives with you? Do you have small children or other animals? Certain dog breeds do better with ...

With the rapid expansion of feline and canine genetic disease testing popularity over the past several years, today it is more common than ever for veterinarians to be asked to interpret genetic test results for their clients and offer recommendations based upon the results. However, the team at Paw Print Genetics (PPG) realizes that genetic counseling has not been a traditional part of veterinary education. For this reason, PPG offers no-cost genetic consultations for veterinarians and veterinary staff to assist their clients with genetic questions. Here we will discuss some of the many factors to be considered when assisting the veterinary team with interpreting genetic test results, assessing disease risk, and making breeding recommendations for the 300+ genetic tests offered at PPG.

Disease Inheritance

Understanding exactly how a specific disease is inherited by offspring can alter your assessment of disease risk and recommendations for breeding. The most common inheritance types discussed in animal genetics are autosomal recessive, autosomal dominant, and X-linked recessive inheritance. However, less common inheritance patterns may also be seen for some animal diseases. Disease risk in animals inheriting one copy of a disease-associated mutation varies based upon the specific mode of inheritance. For example, dogs carrying one ...

Our dogs, our cats, our birds. They are more than just pets – they are our family members! Today, April 11th, we celebrate National Pet Day. The ones who bring us joy, laughter, and even snuggles. What would we do without our pets? Although they may not be able to live forever, we can do our best to give them long and healthy lives. At Genetic Veterinary Sciences, Inc. (GVS), we provide resources to achieve optimal canine, feline and avian genetic health to do just this. We do this through the genetic testing that we have developed for dogs, cats and birds.

What is genetic testing?

Genetic testing allows us to look into the DNA of your pets to learn about the inherited diseases they may have. We can also genetically test to learn about traits your animal may carry for such as coat colors. Our company differs from others as we follow the standards and guidelines for canine clinical testing laboratories, based on human diagnostic standards. This means all of our testing is of the highest quality and accuracy possible.

Why should I test my pet?

A common response we receive when discussing the benefits of genetic health testing is ...

As of January 2021, Paw Print Genetics (PPG) is proud to offer 44 new inherited disease tests for the canine health and breeding community. While these new tests are associated with diseases identified in dozens of breeds, the population size of each breed and the relative frequency of these mutations in those populations mean that some of these diseases are much more likely to be seen in clinical veterinary practice than others. Here we will highlight five diseases from the recent PPG test additions that are among those most likely to be diagnosed in the veterinary hospital setting.

Cerebellar Degeneration- Old English Sheepdog and Gordon Setter¹

A genetic mutation in the canine RAB24 gene is associated with a juvenile-onset, autosomal recessive form of cerebellar degeneration (CD) in two seemingly disparate breeds, the Old English Sheepdog (OES) and Gordon Setter (GS). Also referred to as hereditary ataxia or cerebellar abiotrophy (CA), CD presents between 6 months and 4 years of age with progressive neurological dysfunction due to degeneration of cerebellar neurons, especially Purkinje neurons. Coordinated movement becomes progressively more difficult as the disease progresses and can include intention tremors, ataxia, and a stiff, high-stepping gait (hypermetria). Affected dogs are often ...

Paw Print Genetics has launched 44 new inherited disease tests and two new trait tests for various breeds.  With nearly 300 different tests for more than 350 breeds of dog, Paw Print Genetics (PPG) continues to be the leader in providing genetic tests for dogs.  Here are some of the new tests being offered.  You can find these new tests for your breed under the category “Additional Disease Tests” on your breed-specific page on our website.

New Trait Tests

PPG has launched Saddle Tan (A^s locus) and Intensity (I locus) as part of their large number of coat colors and traits offered for various breeds.  Both of these genetic loci modify a dog’s coat color based on their genotypes at other coat color genes. For Saddle Tan, the variation in the RALY gene will modify a dog’s coat presentation only if the dog also has tan points (k^yk^y at the K locus and a^t/a^t or a^t/a at the A locus).  Sometimes called creeping tan, a dog with one or two copies of the A^s variant and tan points may show a ‘shrinking’ dark saddle across ...

As a laboratory that works directly with breeders and dog owners, Paw Print Genetics (PPG) is often asked to reassure the customer that our tests accurately determine whether a dog will get a disease.  The customer is actually asking a couple of different questions; one involving the accuracy of the test itself and one regarding the clinical validity of the test. It is important to understand the questions being asked so that the answers make sense.

The first question being asked is: Does the test perform accurately to determine if a dog is normal/clear, a carrier of one copy of the mutation or at risk, having two copies of the mutation. At PPG, our tests are extensively validated and must show 99.9% specificity and sensitivity before being available for ordering. Sensitivity is defined as the proportion of samples with a known mutation that are correctly classified/identified as carrier or at risk by their genotypes. Specificity is defined as the proportion of samples with no known mutation that are correctly classified/identified with the wildtype (normal) genotype for the disease.  This all refers to whether the test result accurately reflects the true genotype of the individual. At ...

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 ...

Paw Print Genetics is special and I am not just saying that because I am the CEO. There is no other canine genetics laboratory like PPG. Seriously!  Paw Print Genetics is the only laboratory that has implemented human-based testing standards. What does this mean?  It means that PPG tests each mutation region twice with two different methods to ensure the highest accuracy possible. No laboratory can boast 100% accuracy, but PPG achieves 99.9% accuracy each and every day. This means that you can trust your results and use them confidently in your breeding program. In addition, PPG employs both PhD Geneticists and licensed Veterinarians on staff, in our offices, that oversee the testing and report the results. You can also call and speak to them if you have any questions or concerns. Finally, I am the only board certified geneticist in the canine field; I am board certified by the American Board of Medical Genetics. These three aspects - the 'double check testing', having geneticists and veterinarians on staff, and having a board certified geneticist on staff - are equivalent to the requirements found in human genetic testing laboratories.

In addition to our high testing standards and customer access ...
