We don’t have rules against explicit blogs submitting dog photos because after all we are a dog blog and dogs aren’t explicit? But if it bothers you personally block the blog or just avoid clicking on blogs with blurred avatars as that is a dead giveaway.
No its just a nose and skin. We love dogs with noses and skin tones of all colors. That cute kiddo just as a vibrant one and the pic may be edited as well.
