Hello,
I am considering rescuing a border collie cross, mum is white factored border collie, dad is unknown. Most of the pups have only black patches around the face and base of the tail (see photo when they were born, they're still the same color few weeks later, no cattle dog coloring). I have read that lack of pigment can cause deafness or blindness, I just wanted to know a bit more about it. Any good information around?
If I do the BAER test, would that ensure that the pup will have normal hearing for the rest of his/her life (except normal hearing loss) or can it be degenerative? And with the eyesight? I have read of some white factored dogs going blind at a young age?
Some pups have pigment around both ears and eye, are they still at a higher risk than other dogs?
Thanks for your help!
