Irish Jack Russell Health

Patellar Luxation - Can be caused by an injury or malformation  of the femur or tibia.  Basically the patella jumps/moves out of the grooves meant to hold the patella in place.  Once checked by a veterinarian the results can be certified with OFA if you desire. 

Congenital Deafness - Mostly white dogs can suffer from deafness but all dogs should be tested regardless. This test is referred to as B.A.E.R (Brainstem Auditory Evoked Response) and is performed by a Veterinary Neurologist at at least 35 days old.  Once checked by a veterinarian the results can be certified by OFA if you desire and are good for life.  Our dogs also have their hearing BAER Tested and their eyes CERF tested.

Absence of Premolars - Missing one or more molars.  This can be checked by a veterinarian.

Aggressiveness - Overly aggressive with other dogs or people and may overreact by biting.  These dogs react in a severe manner and are difficult to control.  All our dogs complete a personality profile!

PLL - Primary Lens Luxation - Fibers  that hold the lens in place called Zonules may stretch or break causing the lens to move.  Immediate Veterinarian care is needed and the lens must be removed.   DNA testing is available and can be certified by OFA if desired.

Heritable Eye Disease -   There are many eye diseases dogs can inherit so it is important that all breeding dogs have their eyes examined. This testing is referred to as CERF (Canine Eye Registration Foundation) and is performed by a Veterinary Ophthalmologist at 12 months of age and every year thereafter.  Once tested you may register the results with CERF directly.

Thyroid Disease - Hypothyroidism is most commonly caused by Autoimmune Thyroiditis.  This disease tends to manifest in dogs between 2-5 years of age.  Periodic testing is suggested because a dog that tests negative at 1 year may test positive at 5 years.

CBC - The CBC (Complete Blood Count) blood test for dogs, checks the number and types of red and white blood cells present in the dog. This test is important when diagnosing illnesses or infections so it is important to run this test on all dogs as baseline for comparison in the future should a dog become ill. 

Blood Chemistries-  A blood chemistry looks at things like electrolytes, liver function, kidney function and the dogs overall metabolism.

Brucellosis - Is an infection found in dogs caused by bacteria (brucella canis).  It is spread through mucus membranes during mating, maternal milk and discharge from the uterus of infected bitches. 

In female dogs it can lead to early death of infected puppies and abortion unborn puppies.  In male dogs it can lead to infertility.  Once a breeding dog contracts this disease they can no longer be bred.  We test our dogs for Brucellosis prior to breeding.

OFA  Certification (Orthopedic Foundation for Animals) - OFA is a not for profit organization with focus on the health and wellness of animals through genetic testing.   They maintain a database of genetic test results  which breeders and pet owners have submitted in an effort to reduce the incidence of inherent diseases. 

OFA's four specific objectives:

* To collate and disseminate information concerning orthopedic and genetic diseases of                 animals.
* To advise, encourage and establish control programs to lower the incidence of orthopedic          and genetic diseases.
* To encourage and finance research in orthopedic and genetic disease in animals.
* To receive funds and make grants to carry out these objectives.

While certification with OFA is important it is not mandatory but rather completely voluntary.  Our Irish Jack Russell Terriers or Shorty Jack Russell Terriers are OFA certified for the following:  Thyroid Disease and Patellar Luxation and Primary Lense Luxation.

Did you know:

English Jack Russell Terrier, Irish Jack Russell Terrier, Shorty Jack Russell Terrier, Puddin Jack Russell are all names for Jack Russell Terriers.  These names all refer to a dog longer than tall however the Connemara Jack Russell Terriers hail from very different bloodlines.  Ours have the DNA test results to prove it!  The Connemara Terrier is a mild tempered, gentle companion dog that makes a great family pet.

All of our Irish Jack Russell Terriers or Shorty Jack Russell Terriers (as they are sometimes referred to as) undergo several health tests to ensure our breeding stock is healthy and free of disease.  These tests and the processes involved are part of our commitment to breeding these fine terriers.

Below you will find a list of diseases we are currently able to test for, most without the use of DNA.  These tests are readily available so we take full advantage of that and test all our Shorty Jack Russell Terriers.
Disease Screening: We also use the DNA testing offered by Shelterwood Laboratories using VeriSNP universal screening.  This testing can identify 29 different diseases and identifies color traits in the animal.  Most of these tests are breed specific but some can be identified in many pure breeds as well as mixed breeds.
