It’s easy to see why the beagle has been ranked near the top of AKC registered dog breeds since their acceptance in to the AKC registry in 1885.  Their amiable personality, fantastic sense of smell, and natural talent as a hunter and guard dog have kept them popular with American dog lovers for the past 130 years. Unfortunately, like most popular, purebred dog breeds, particular inherited diseases can make life tough for some beagle blood lines. Luckily, the genetic cause of some of the beagle’s known inherited diseases have been discovered. Thus, allowing laboratories such as Paw Print Genetics to develop genetic tests that allow for the elimination of these disorders through informed selective breeding. The following genetic tests are available at Paw Print Genetics:

Musladin-Lueke Syndrome

One of the largest inherited disease concerns for beagle breeders is a disease known as Musladin-Lueke Syndrome (MLS). MLS is listed on the Canine Health Information Center (CHIC) as a required test for the beagle and is typically identified in affected puppies by 2 to 3 weeks of age. MLS is a connective tissue disease that causes stiff, contracted joints, and inelastic skin giving affected dogs a characteristic tip-toe walk described as ...

If you are a dog owner that values intelligence and obedience above all else when choosing a dog, it’s likely you are familiar with the border collie. This hardworking canine breed who received its name from its likely place of origin along the border of England and Scotland, has historically been bred for working ability above all and is widely regarded as one of the most intelligent breeds in the world. Though generally considered a relatively healthy breed, like other purebred dog breeds, the border collie is known to inherit several genetic diseases; some of which are known to be caused by specific genetic mutations. Discovery of the specific mutations responsible for genetic diseases allow laboratories like Paw Print Genetics to develop tests to identify dogs that carry the mutation. This information allows breeders to selectively breed these carrier dogs to dogs that are clear of the mutation in order to avoid producing puppies with these diseases. Three specific inherited diseases are listed on the Canine Health Information Center (CHIC) website as optional recommended tests for the border collie. Testing for these diseases is available from Paw Print Genetics:

Collie Eye Anomaly

One of the biggest inherited disease concerns for ...

Since we opened Paw Print Genetics in April of 2013, we have had the opportunity to work with many breeders and other dog owners who already had previous experience with genetic testing of their dogs. Though the vast majority of these clients have praised us for our ease of ordering, unrivaled customer service, and quick test results, some clients have expressed some confusion in regards to why (or how) we use cheek swabs as our default method of DNA collection opposed to other methods that they were already familiar with.

In The Beginning

When making choices about how Paw Print Genetics would operate, we decided we wanted to eliminate as many barriers to canine inherited disease testing as possible. Not only did we want to make testing more convenient by offering as many disease tests as possible under one roof, we also wanted to make the experience of DNA collection easy and more convenient. To accomplish this, we chose to allow our clients to collect DNA in their own home or kennel with cheek swabs we provide (at no additional cost) after an order is placed. This decision eliminates the time, effort, and expense our clients had previously had to ...

In part 3 of this series of blogs about itchy dogs, we took a look at two common parasites of dogs; lice and mites. In this fourth and final part of these blogs we will discuss fleas and ticks, two other common parasites that can make our dogs’ lives miserable at times.

Fleas

Though there are multiple species of fleas that can infest our dogs, the most common flea type in North America is the “cat flea”, known to scientists by the name Ctenocephalides felis. Fleas are commonly acquired by our dogs through close contact with other infested animals or from environments suitable for flea development and dormancy. Regions with higher environmental temperatures and high relative humidity allow fleas to develop more quickly and to survive for extended periods of time off of a host. Once infested, there are two important pieces of information that should be considered to eliminate fleas and prevent a reinfestation of your dog; flea control on the host and flea control in the environment.

Since female fleas must take a blood meal before they can lay eggs, controlling the fleas ...

Though many itchy dogs suffer from food or environmental allergies (as discussed in previous blogs of this series), parasites of the skin and hair coat (called ectoparasites) are another important cause of itchiness in our canine companions. In fact, performing parasite testing should be considered a veterinary standard for itchy dogs. Ruling out parasitic causes of itchiness is important because they can greatly complicate diagnosis and treatment of other skin related diseases. Though there are many individual species, in this and the next blog in this series we will examine four general groups of ectoparasites that infest our dogs.

Lice

The first experience I can recall involving lice was in elementary school; a time period in life when an infestation of head lice could turn any otherwise sanitary, well-meaning child into the classroom leper. Luckily for us dog owners, we don’t need to fret much about our own health if our canine children come down with an infestation of lice as they tend to be very species-specific in regards to which creatures they choose to call home.

Lice come in two main varieties; chewing lice and ...

Customer service is of the highest priority at Paw Print Genetics. From the numerous positive reviews we have received on our Facebook page referencing our personal attention to detail, to the many emails we receive from our clients thanking us for a job well done, we recognized early on that we were on to something. After all, we know that without our loyal clients, we could simply not exist as a laboratory. The customer service goal established by our company culture is to exceed the expectations of every client that we have the privilege with which to work. We want our clients to come back to us for genetic testing, not because we are the only option, but because they have never had a better experience with a genetics laboratory.

Though the pursuit of exceeding client expectations is an ideal that most businesses strive for, the exact way to perform this level of service often remains elusive. In addition, there has been a long standing debate about whether the skills needed to provide great customer experiences are ones that can be taught or learned. One veterinary nonprofit organization, the Veterinary Leadership Institute, has helped prove that not only can these ...

Like people, some dogs are known to develop seasonal summer allergies to a variety of environmental allergens. Pollen, mold, dust mites, and mildew are just a few of the triggers that can make dogs itchy as the days become warmer. Many dogs have only mild signs of allergies that can be controlled by the use of antihistamines and bathing to wash allergens from the hair coat. In these mild cases, the allergies are predictable annually, they don’t seem to progress in severity, and are relatively easy to manage. However, for some dogs, the body’s reaction to allergens is so significant that their overall quality of life can be greatly impaired.

Canine Atopic Dermatitis
An allergic disease now termed “canine atopic dermatitis” (CAD) is a relatively common and troubling condition seen in our canine friends. It is estimated that up to 10% of all dogs are affected by this condition worldwide. First discussed in the 1930’s, the definition of the disorder and our scientific understanding of the cause are still being worked out. Our current understanding is that CAD is a multifactorial disease involving genetic predisposition, immune system dysregulation ...

The summer season is upon us! Unfortunately, for many dogs, this also means the itchy season. In 2013, according to the veterinary health insurance company, Veterinary Pet Insurance (VPI), trips to the veterinarian for skin allergies were the most frequently submitted claims. In addition, the second highest number of claims came from owners whose dogs had ear infections. Interestingly, one of the most common causes of ear infections in dogs is also allergies.

In my experience, there are many misunderstandings among dog owners when it comes to canine allergic disease. One of the most common misunderstandings I encountered in practice was to blame food first as a cause of their dog’s bad skin. It was not uncommon for an owner of an allergic dog to inform me that they had already changed their dog’s food multiple times, but that it either didn’t help or only helped for a short period of time. Not only can rapid food changes cause severe gastrointestinal issues in dogs, approximately 90% of the time owners are wrong in blaming food, as only 10% of all canine skin allergies are believed to be food related.

Grain-based foods tend to get an unfair portion of blame. Though ...

Since its origination as a rodent hunter in the late 1800s, the German-bred miniature schnauzer has become one of the most popular dog breeds in the United States. Believed to originally have been developed by breeding the standard schnauzer with the smaller affenpinscher (and possibly the poodle), the miniature schnauzer is a hardy, tenacious breed with an energetic, playful personality. Often appreciated for their natural aptitude as watch dogs, miniature schnauzers can be great family pets. 

Unfortunately, like most popular dog breeds, the miniature schnauzer is known to develop some inherited diseases that can create difficulties for the breed and the people that love them. Luckily, several inherited diseases in the miniature schnauzer have had their specific genetic mutation identified and can now be prevented in puppies by testing dams and sires and using informed selective breeding techniques. Carriers of recessive genetic diseases (diseases in which the offspring must inherit one copy of the genetic mutation from each parent to show signs of disease) are particularly troublesome for breeders because despite the fact that parents carrying a single copy of a disease causing mutation are not affected by disease, they can still pass the mutation to offspring and produce ...

Basenjis are an ancient, charming and unique breed originating in Africa. According to the Basenji Club of America, dogs resembling basenjis have been found in African cave paintings and Egyptian art dating back to between 1000 and 6000 BC. In the late 1800’s, the German botanist and ethnologist, Georg Schweinfurth described a domesticated dog closely resembling the Basenji belonging to native people of central Africa that he had encountered on his trips to the region. Shortly after this description was published, dogs resembling Basenjis were exported from Africa and displayed in Great Britain and Berlin as “Lagos Bush Dogs” and “African Bush Dogs” respectively. Despite their unique and desirable characteristics (such as their yodel-like vocalization known as a baroo), basenjis are similar to other dog breeds in the sense that they are known to inherit a handful of genetic diseases that can cause significant issues in breeding programs. Luckily for the basenji, genetic tests are now available through Paw Print Genetics to help breeders prevent future generations of dogs from being born with some of these preventable illnesses. The two inherited disease tests recommended by the Basenji Club of America and of great importance for basenji breeders have been the ...
