Some of the most emotionally challenging canine cases seen in the veterinary hospital are those involving serious illnesses of newborns or young puppies. Owners’ joyous expectations of a long, healthy relationship with their new puppy makes a disease which decreases that puppy’s quality of life or results in early euthanasia, all the more heartbreaking. Though infectious diseases like parvovirus are often of particular concern in young pups, some puppies ending up on the exam room table show signs of one of a wide array of inherited diseases caused by a known genetic mutation. Unfortunately, limitations in available therapies for many inherited diseases often lead to frustrating and emotional outcomes for all the parties involved; veterinarians and veterinary staff included. Thereby, making prevention of inherited disease through the use genetic testing, an essential part of healthy dog breeding.

Historically, methods to prevent inherited diseases have been limited to selective breeding practices. However, an inability to identify asymptomatic carriers of recessively inherited diseases or dogs in the preclinical phase of late-onset inherited diseases, have traditionally made great reductions in disease incidence difficult to obtain through selective breeding alone. Genetic testing is now playing an important role in identifying these dogs such that ...

The liver disease, copper toxicosis (CT) has become a hot topic among Labrador retriever breeders and dog owners with the arrival of a new genetic test which identifies two recently described mutations found in Labradors associated with opposite effects on the amount of dietary copper stored in the liver. As with all new canine genetic tests, questions and concerns may arise from breeders about how to interpret their dog’s test results, how to use this information to maintain the health of their dog, and how to use the information for their breeding program.

What is liver copper toxicosis?

Copper toxicosis is an inherited metabolic disease affecting Labrador retrievers and other breeds, which can result in chronic liver failure. Dogs with copper toxicosis have a decreased ability to excrete dietary copper from the body resulting in excessive copper storage in tissues and organs, including the liver, which can result in liver damage, subsequent cirrhosis and the inability of the liver to function properly. Though the age of onset and speed of disease progression are variable, most affected dogs will present in middle age with non-specific signs of liver dysfunction including weight loss, lethargy, weakness, vomiting, diarrhea, and abdominal pain. In late ...

The clotting disorder known as von Willebrand disease (vWD) is a relatively common and potentially lethal disease of dogs. Three general types of vWD (types I, II, and III) have been described based upon the specific genetic cause and level of deficiency in a protein known as von Willebrand factor (vWF), which plays an important role in blood coagulation. Dogs deficient in vWF protein are at risk of potentially life-threatening bleeding episodes when undergoing surgical procedures or as a result of traumatic injury. Therefore, when a relatively high frequency of Boykin spaniels was identified in the Paw Print Genetics (PPG) laboratory to carry a mutation in the VWF gene previously associated with vWDII in German shorthaired and wirehaired pointers (Kramer and colleagues), Boykin spaniel lovers and our team at Paw Print Genetics (PPG) were understandably concerned.

Concern turned to confusion as Boykins expected to be at risk for vWDII (based upon their genetic testing results) failed to show any signs of a clinical clotting disorder. In addition, results of additional blood tests looking at the product produced by the gene on several “at-risk” dogs showed no deficiency in vWF protein and no increase in blood clotting times. At that time ...

The following is a letter written by a Paw Print Genetics' customer, Justin Riegsecker, posted here with his permission.  Click to find out more about JARS Labradoodles.

I started JARS Labradoodles three years ago when I purchased my first Australian Labradoodle stud.  I am very fortunate in that my father has been a breeder for over 43 years - fortunate because he allowed me to get started by essentially giving me three amazing Moyen Poodle females.  More importantly, I am fortunate because he has taught me many things about raising puppies and how to deal with the unexpected.  I'm sure you know the proverb about the difference between giving a man a fish or teaching a man to fish.  I really feel like I was given the fish AND taught how to fish.  Our business has grown over these three years and I've merged JARS Labradoodles with my father's Goldendoodle breeding program. 

My father is old school - doesn't know much about the internet and the power to reach millions of potential clients across the United States.  I have a Bachelor's degree in business and marketing and had spent several years in sales prior to ...

Providing a unique DNA profile to identify a dog or performing paternity to qualify a sire is not new. In both humans and canines, these services have been around for decades, but so has the technology.  The use of microsatellite markers has been the mainstream technology for identifying people and dogs since the early 1980’s.  However, these particular markers are best used to exclude a suspect or exclude a sire, but trying to prove identity or prove that a sample is from the one and only possible sire is much more difficult.

Welcome to the 21^st century!  The old microsatellite markers were just not good enough, in some cases, to distinguish a sire from his sons or brothers from one another.  And in true Paw Print Genetics fashion, we are just compelled to do everything better than anyone else! Introducing single nucleotide polymorphisms, or SNPs. These are small changes in the DNA that tend to be different between individuals, including relatives.  Paw Print Genetics is using a proprietary set of 99 distinct SNPs found in different locations throughout the canine genome to uniquely identify individuals and better qualify sires.

Since we started working with the Boykin Spaniel Society (BSS), both Paw Print Genetics (PPG) and the BSS have learned much about the genetic disease concerns of these wonderful, little brown dogs. By using the founder breeds of the Boykin as a guide, PPG developed the first Boykin spaniel inherited disease testing panel in 2014. Based upon the results collected over two years of testing Boykins, in September 2016, the original disease testing panel was split into two panels; the Boykin spaniel essential panel (containing the most clinically important and/or common diseases) and the supplemental panel (containing diseases of less clinical importance and/or lower incidence).

Two of the four diseases on the Boykin spaniel essential panel are inherited diseases of the eye. Diseases resulting in vision loss or blindness are among some of the most life-altering and troublesome non-lethal diseases of dogs. However, with knowledge of a specific genetic mutation resulting in blindness as well as an understanding of how that specific eye disease is inherited, blindness caused by the mutation can be prevented through the use of genetic testing and informed selective breeding practices based upon test results. Two eye diseases known to be inherited in the ...

At Paw Print Genetics, we are so thankful for our customers. Without you, we simply wouldn't exist. Without your input, we wouldn't have some of our recently launched programs such as Veterinary Verification reporting, Paw Print Pedigrees and Clear by Parentage certificates, as these, and many other features and tests that we offer have been suggested by our customers.  We see our customers as our partners, suggesting changes, tests and features that enhance your testing experience with us.  

After a report has been issued, I send each customer an email thanking them for their business and for their commitment to healthy dogs.  These take time, but I feel that these emails are important to send. The emails remind me of how important it is to connect with our customers, to reach out to see if there is anything else that we can do for them, to ask if there are ways we can improve our service, and to provide a little reward for being a responsible breeder with a discount on their next order.  Will I be able to keep this up as we grow?  I hope so.  It provides such a great opportunity to get feedback from our customers and I receive ...

You’ve spent a small fortune and an immense amount of time selecting, purchasing, socializing, and training your young Labrador retriever, Charlie, for the big hunt. It’s the first hunt of his career and he’s amped! As you are getting everything out of your truck, you let Charlie out of his crate to run around and explore a little. He disappears for several minutes as you are getting your gear and you call him back to you. However, when he returns, you notice that Charlie seems wobbly in his rear end and eventually his hind limbs collapse. He attempts to keep running, but drags his hind limbs for a short distance before giving up and lying down. Uncharacteristic for Charlie, he won’t get up when you call him and he no longer seems to be as interested in the hunt. After comforting Charlie for several minutes, he gets back up on his feet, though you can still see that he is a little wobbly. After several more minutes, Charlie is back to his jovial self with little indication that anything was wrong.

Unfortunately, the scenario described here is not a terribly uncommon story among Labrador owners and those that hunt with ...
