Pyrenean Mastiff Public Service Announcement!
Embark has added a new test called Copper Toxicosis or also known as Copper Storage Disease. The reason we want to address this test is because we are seeing markers on dogs who have been tested since it was released in the Summer of 2024.
However, at this time we are in a data gathering stage to better identify how widespread the markers are in the breed. Based on preliminary data gathering we suspect the markers are a false positive in the Pyrenean Mastiff and that this disease does not apply to the Pyrenean Mastiff.
Of 28 known dogs tested since the Summer of 2024, only 28.57% (8) of dogs do not have any markers for the condition. 57.14% (16) of dogs have 1 marker and 14.29% (4) of dogs have 2 markers. This indicates that the marker being identified is fairly widespread in the population based on initial data gathering and has not been linked to any specific country considering the dogs are diverse from each other.
At this time it is almost impossible to avoid breeding a carrier/at risk to carrier/at risk. The reason we suspect that this disease marker does not apply to the Pyrenean Mastiff is due to the fact that there are no known cases of the disease in the breed and considering how widespread markers are we would have expected many cases of it by now.
The Pyrenean Mastiff Pedigree Database does have a field added for data gathering so if your dogs have been tested against this marker you can update the pedigree database to help us continue to get a better understanding of the marker in the breed population.
At this time we do not feel it is mandatory to retest breeding dogs for this marker just that moving forward we continue to gather data for population data.
If at any point a dog is diagnosed with this condition, please notify us! This can only be confirmed via liver biopsy.
Sincerely,
PMAA Board of Directors
Picture for attention because who doesn't love seeing puppies.
