I have never heard of it either.  I know that my Yorkie sometimes lies down in that position (but he is not a puppy).  Did someone say it to you or did you find the info on the Internet?

I have heard it is a sign of good hips

WHAT A BUNCH OF BOLOGNA. MY WINKIE DOES IT ALL THE TIME.

this is not what the original poster is asking about.

Yeah you should discourage the dog from sitting in this posture. Its done usually when the pup is feeling hot to cool the tummy region on cool surface

cheers

Nothing about bad hips. Is it possible he could be gay.

Don't be worried:  it is just someones dipstick opinion and a rumor someone had to start because they were bored

Just like the rumorS:    RAW MEAT FED TO A GSD  MAKES THEM MEAN

RAW MEAT GIVES DOGS  WORMS

A GSD THAT SITS SIDEWAYS ON HIS HIPS WHEN A PUP  HAS   HD

EARS THAT ARE NOT UP WHEN PUP IS 12 WEEKS OLD WILL NEVER STAND WITHOUT  A VET TAPING THEM

"ANYONE THAT POSTS ON THE GERMAN SHEPHERD DATABASE IS AN IDIOT "        QUOTE FROM AN ALIEN NAMED     CLIFFORD

Do not let pup lay like that..do not let pups and youger gsd jump off tailgates or high tables or higher planes of any object.

COCKERS LAY LIKE THAT AND THEY ALSO CAN HAVE   HD ...WELL KNOWN BUT THE HAVE DIFFERENT GROWTH PLATES THAN A GSD.

I have also heard it means they have good hips. It's just an old wive's tale. It is said a lot about rotties as well. Theresa

always consider the source you hear some of these things from..

I am amazed at what I hear from people all over the state of Texas and in dog world...It amazes me how people who own dogs  know so little facts..

Find a very reputable Schutz trainer of a IPO trainer or a well known breeder who has lots of years of awards and many good long lists of references before you believe what seems weird.

If it looks like a duck and walks like a duck and quacks like a duck:

Chances are it is a DUCK
