Is it true?

I never heard this before and I really don't have any idea at all.  I do know two people that had rotties that lived to be quite old and they weren't any different than any other old dog.  Maybe some rottie owners can chime in here ...

OMG how ridiculus!  Brain turns to mush. I find that statement asinine. I had a Rottie as far as brains turning to mush...no!  But seizures can do brain damage to any dog.  Maybe that's what those other people meant.  Rottie's are great but not for everyone.  But you are talking a mix breed so you really don't know which side it will take after since it is a pup.  A dog is what you make of it.  Rottie's are very smart.  Good Luck to you!

Sounds like a myth to me. Any dog, no matter the breed, size, or other characteristics, has the ability to act out. Depending on where the pup is coming from, the chances of you getting an actual cross between a pure Golden and a pure Rott are slim. Unless you really do know the parents or its documented somewhere, the rottie seen in the pup may not be rottie afterall. 

I have goldens, never had a rottie.  However one of my neices has one that is pretty old.  Strange thing is she went gray ON TOP of her head and she looks like she is wearing a gray toupee.  She is a very sweet dog, and her brain is no more mush than mine---if that means anything! LOL.
 
And true, rotties are not for everyone.  I use to walk my dogs, one at a time, and on this one street I loved because it is the last one in town and kinda like being out in the country as there are only scattered houses on one side, woods on the other.  But one yard had a rottie chained in the back and when he saw my dogs, he would run and hit the end of the chain so hard he would be yanked off his feet. and he would stand there snarling and growling.  I got so worried about him breaking the chain i stopped walking my dogs on that street.   Perhaps it was the fact he was chained to that tree 24/7 that made him like that.  Oh, he would just bark if I was walking alone, not a threatening bark, just a bark.

I am thinking about adopting a golden retriver/rottwieler mix. I was advised not to because of the rottweiler and that when rotties get older their brains kind of turn to mush and they forget who cares for them, etc. and will hurt that person to defend themselves. Is this true? If so, would the retriever's genes dominate the rotties and keep this from happening? Or is adopting this puppy not a safe/wise thing to do? I have plenty of other puppies to chose from if adopting this one would end up badly.

 
That is the biggest pile of poop I've ever heard. It is a known fact that there are a lot of peopl scared of specific dogs because of they way they are portrayed in the media, in movies, and becuase of there size. If you TRULY believe that such a thing is even possible then I suggest getting a dog that you would feel more comfertable with. I'm saying this because it wouldt be fair to you or the dog to go into this relationship with doubts. He will never doubt you if you show him the love and compassion ALL dogs deserve.
I own a pit bull oooohhh, watch out, ha ha. She is the sweetest dog you would ever meet, she chaes and plays with children we know at the park and would never hurt a fly. YES she does have the strength to do some major damage to people and other animals, will she? No because I have made her part of our family and taken the necssary steps to ensure that she is well socialized, healthy, and obediant.
Good luck with your new pup whatever you choose and don't forget to post pics, we love pups!

I really didn't think it was true.  My older brother told me this, and he does know a lot about dogs so I thought I'd rather be safe than sorry and check his theory out rather than just go ahead and set myself up for a possible crash and burn. I dog walk at our Humane Society and the puppy is in a kennel all by himself and he's been there for about a week.  There are tons of puppies I play with there and they're all adorable, but of course your heart reaches out to a certain one. Well thanks everyone! I think I'm going to go ahead with the adoption.  This little guy is worth anything
