Pitbulls are the sweetest dogs ever if raised right, just saying..
I've never really gotten bad advice. My local Petco is actually a pretty good store, besides the fact that they keep many baby corns in the same tank. The only bad advise I've gotten from them is tht astroturf is the best substrate, which isn't all that bad, since astroturf is ok even though aspen is better.
Well, it's not entirely on how you raise it... there is a certain amount of genetics involved.
If you breed to physically unstable / mentally unstable dogs there is a chance that the offspring might be just as bad - or worse.
I own a pit-type dog. I got her from some one who had no business breeding animals. She
is a sweetheart, but she is also a complete basket case when separated from her people.
She has really terrible separation anxiety.
I am fairly certain that I did not raise her to eat her own tail when left alone during the course of the average work day (I'm a stay at home-r now).
Just saying.
Every dog has a different personality, just like people.
The worst advice I ever had concerning reptiles...
Well, I had some one try to tell me that my (late) red legged running frog wasn't nocturnal AND was native to California - not Africa. And that it didn't need a long tank.
Fortunately I haven't heard any wild tales about my corn... but I did have a pet store employee tell me that platy fish wouldn't breed in filtered water 0.o
