Sight Issues With Merle/Merle Miniature Australian Shepherd
Hello, I have an 8 month old Miniature Aussie. She is a blue merle without any brown marking, her mother was a red merle and father a blue merle. I was wondering if a red merle/blue merle cross would result in puppies with sight and hearing problems as well. My pup has good hearing but she does squint when the lights are turned on and it seems to take her a while to adjust. I'm just looking to find out if this could be a problem or if it is normal for a dog to squint or take longer to adjust to different brightness of light.
