Why Do Dogs Have Black Spots on Their Tongues?

bootleg spot on a wiener ’s tongue are created by pigmentation and , to some degree , determine by genetic science . They ’re not always present at birth but can develop during the first several month of living .

" Genetic factors play an important character in frump breeds that develop an hereditary blue - black pigment spit ( typically in the first 6 calendar month of life ) , " Carl says . " A area hold back several genes has been consociate with spotted and fully pigmented tongues in chows and some related strain , but no specific genes or inherited variants have been shape to fully explain these traits . "

As for why some frump have amply pigment natural language and others merely have spots , it ’s also plausibly related to genetics . " There is grounds to propose that specific combinations of multiple genetic variants may excuse deviation between pink ( unpigmented ) , spotted , and fully pigment tongues . There may also be independent gene that are associated with spotted glossa , " Carl say .

luckily , the natural development of blackened spots on a dog ’s tongue is not harmful to the dog and does not affect their health or behavior .

Over time and many generations , this practice can eventually ' fix ' a trait in a stock result in all ( or nearly all ) members of the breed reliably developing that trait . "

Lots of dog-iron breeds are known for pigmented tongues , many of which have Asian ancestry , and this trait can rest when those dogs are mixed with other breeds .
