Did you see the dogs or pciture of the dogs with blue eyes. I have many pictures of my Mastiff when he was a pup and his eyes look baby blue, but in reality they were not. The recessive gene associated with Danes & Blue eyes does not automaticaly equate to a hearing issue. Odd;s are if the pup can hear when they are young they will not develope an issue down the road.
I have generally stayed away from getting a great dane with blue eyes, as in some cases it can indicate deafness. However, can it be normal/safe for English Mastiffs or Mastiff/Great Pyrenees to have blue eyes? I've seen some beautiful Mastiff and Mastiff mix puppies with blue eyes but am wary in case they will be deaf.
Also, if you could share your experience or site any sources that would be really helpful. I'm not finding much info online on mastiffs with blue eyes specifically.
Thanks in advance for any input!
