choc. lab puppy kicking back legs

Question
QUESTION: My 12 week choc. lab puppy kicks her back legs after using bathroom and eating. What is this all about? thanks

ANSWER: It could be a form of marking.  In addition to leaving the scented waste, dogs may also leave visual marks as scrapes.  12 week olds are still sorting things out and often show behaviors you would expect of an older dog.

QUESTION: in your professional opinion, is there any difference in intelligence level in the three lab colors? thanks

Answer
I am not a professional.  I am highly experienced and much of it has been with some of the best professionals around, mentoring me.  They claim chocolates are hyper and more prone to joint problems.  Other highly experienced people claim there is no difference.  To really give a good answer to your question, you would need to give an accurate test to a large sample of Labs.  I doubt that has been done.  I also doubt if it was, there would be much difference.
