The canine population can be just as susceptible to health issues as the human population. And, as with humans, some of these health issues are genetic. The Wheaten Terrier is no exception. Mandatory health testing is one way SCWTCA sets the bar high for its member breeders. The club requires its members to abide by a strict Code of Ethics wherein member breeders are required to complete all health testing on their breeding stock. The results of this health testing should be found online at SCWT Database. While it is not possible to avoid all genetic disease, the SCWTCA breeder greatly reduces the risk of these diseases to the puppy through these tests. By choosing a SCWTCA breeder you gain a partner for the life of your puppy. Choose carefully, ask the right questions and refer to the online SCWT Database or ask the breeder directly for health testing results.

RECOMMENDED Health Screening for Breeding the Soft Coated Wheaten Terrier: When the recommended screenings are done on the parents, the puppies produced have a decreased risk of health issues. These tests are recommended by the SCWTCA for breeding stock.

Microphthalmia Syndrome (MO) Degenerative Myelopathy (DM) Paroxysmal Dyskinesia (PxD) Biochemical Profile (Chem Screen), Brucellosis, CBC, Urinalysis, UPC/MA
Who to test Either or both sire and dam Either or both sire and dam Either or both sire and dam Both sire and dam
Testing frequency Prior to first breeding Prior to first breeding Prior to first breeding Brucellosis prior to every breeding

Blood and urine test of dogs with no PLN test or with PLN markers should be repeated more often, perhaps 2 or 3 times annually after 2- 3 years of age.*

PennHIP radiographs may be performed by a PennHIP trained veterinarian as an alternative to OFA x-rays. A higher distraction index indicates greater hip laxity and an increased risk of developing hip dysplasia with osteoarthritis. There is a low risk of developing hip dysplasia with osteoarthritis when the distraction index is close to 0.30. The Mean Distraction Index for Soft Coated Wheaten Terriers is 0.54, but this can be a fluctuating number depending on how many Soft Coated Wheaten Terriers have been tested using PennHip at any given time.

Clear By Parentage (CBP): If both parents have been DNA tested “clear” for a disease and the lab testing results have been submitted to the SCWT Health Database, then offspring may be considered Clear by Parentage. Clear by Parentage applies for 1 generation only per the SCWTCA Code of Ethics. The SCWT Database does not use the term “clear by parentage;” instead, dogs whose sire and dam have no markers are referred to as having 0 markers by parentage.

CAER Eye Certification with Breeder Options – A CAER eye certification result may be Normal with Breeder Options. The dog’s eyes are certified, however you may want to refer to the OFA website for current guidance on ideal matings for that specific eye condition. See link above.

*Annual Blood CBC, Chemical Profile, Urinalysis and Urine Protein Creatinine Ratio/Micro-Albumin Test – Testing definitions: CBC – Complete Blood Count. Chemical Profile – Chemical Profile which includes Albumin, Cholesterol, Amylase, Lipase, na/K ratio, Creatinine, and Total Protein. UPC – Urine Protein Creatinine Ratio or MA- Micro-Albumin Ratio. Recommended testing is as presented by Dr. Meryl Littman VMD DACVIM, May 2022, Webinar.

Degenerative Myelopathy Testing Research: Research on DM and the genetic testing for DM markers is ongoing. Some of the research is focused on the risk factors that cause the presentation of the disease and its association with the genetic DM markers as tested. See link above.

CHIC Certification (Canine Health Information Center): A dog achieves a CHIC Certification if it has been screened for every disease required by the parent club for that breed and the results are publicly available in the OFA Database. For the Soft Coated Wheaten Terrier, the SCWTCA requires hip certification, PLN variant gene test, and CAER eye certification.
