Why do some have floppy ears and some have pointed????

just a guess but,

Why do some people have blonde hair, and others brown?

I think its probably down to genetics :)

No its due to the pointed ones being cropped. Gillian

In the USA it is a fashion to have the ears cropped whereas it is illegal to have that done in the UK :)

I am glad it is illegal here from what i know it is not very pleasant, bits cut out of the ear i think, they look much friendlier with normal floppy ears :-)

Dee dee, that croped ears are not ment to look friendly ;)  ment to look like a nasty guard dog!!! :) (as if a dane could do any harm....)

"only to shoes".

And bushes in the garden, wellingtons, toilet rolls are good, pegs on the washing line, telephone directories, fluffy toys, slippers, feather pillows, door frames, plaster on the walls but only after the paper has been pulled off and basically anything they can get in their mouths.
