With our recent new mottled addition, I wanted to bring up the conversation about white Australian Cattle Dogs (white heelers) and the potential risks associated with excessive white patterning in the breed!
Iβve personally always been cautious about producing white heelers, even back when I worked with off standard colors, because excessive white can be associated with increased health risks. These risks can include congenital deafness, vision issues, light sensitivity, and increased sun related skin problems due to reduced pigmentation and pink skin! Matter of fact those who know me knew I used to hate mottled dogs too even before, I only fell in love with them after my Arlecchino who passed away last year, she made me love them!
All Australian Cattle Dog puppies are born predominantly white, but as they mature they typically develop their blue or red speckled/mottled pigmentation. A true white heeler remains heavily white into adulthood with very limited body pigment, often alongside pink skin and reduced coloration around the ears, eyes, or nose
Careful pairing decisions greatly reduce the chances of producing excessively white puppies. There have been cases where two speckled dogs unexpectedly produced white puppies due to recessive or hidden genetic factors. Thankfully, there are now genetic tests available that can help identify some white risks, although theyβve become a little harder to locate recently due to testing company merging I believe?
Because of this, we take our breeding decisions very seriously and carefully evaluate pigment, markings, and lineage when planning pairings. We are especially cautious with mottled pairings, as heavier mottling and reduced pigment can increase the likelihood of excessive white markings. For that reason, I will NEVER breed mottled to mottled pairings, and instead only pair mottled dogs to well pigmented speckled dogs in an effort to preserve healthy pigmentation and reduce risk as much as possible. Also some "speckled" looking dogs can be mottled genetically such as our female Nebula, her dam didnt look mottled, but was and produced mottled puppies still!
This isnβt meant to shame anyoneβs dogs every dog deserves love and care regardless of color, but I believe education and responsible breeding practices are important conversations to have within the breed!
