Spotted tongues in Rottweilers?

I have a 6 month old rott puppy. I just noticed spots on his tongue. I have no papers on him, and don’t intend to breed him. I’ve had 6 Rotts in the last 25 years. Never saw a spotted tongue. This little big guy has an awesome personality, he’s is super visual ( looking into Windows and other stuff) … I’m not sure he’s pure bred, but he is a an awesome puppy. He has good heart and super smart. He looked purebred at 7 weeks when we got him. His hips look good too

Growing up in New orleans i remember falling in love with Rottweilers back in 1980 when i lived in uptown New Orleans and my neighbor was a police officer he had a Rottweiler that had a purple tongue an at the time i no there was only one breed that had a purple tongue that was the Chow Chow. As time pass the owner of the rottweiler realize his dog like me so because it was a service dog he was a officer he thought it was always about business. after a little wow i started to go and get him and he even would look for me i had a german shepherd they became best of friends. But i remember my neighbor was telling me the history of the breed he said his great grand father was german and breed them dogs and his dog resembles his great grand father first dog he got from his grand father so we talking early 1900 or late 1800. i remember all the pure breed german rockys had purple tongue and about a year are so later i got my first rottweiler its funny how it happen i was walking down Magazine Street walking my dog and a friend of my was in the car with his mom and she was telling me how her an her husband paid all this money for this dog but they never no it was going to grow that big. his mother no me and my brothers love dogs so she asked me do i want it and can i give it a good home i said hold up really hold up i didn’t no what kind of dog she was talking about i can’t take any kind of dog home she said it’s a rottweiler and do i no any thing about that breed i said yes ma’am and i would love to take him so we set a time so i can go get him 4:00pm i remember it like it was yesterday i got my oldest brother to go with me so we walked over to the Garden District and made it to the house man the first time i saw him i said wow to my friends dad he had a purple tongue like my neighbor dog my friend dad said he came from a town in germany called Rottweil germany and he is the best of his breed and you take real good care of him i named him spark a couple year pass and i got a female and started having puppy’s i have family in Edmonton AB Canada that still have spark blood in them with purple tongue.
