Why do some staffys ears stand up?

I think it's to do with the cartlidge, and the ears don't break over properly.

Megs ears were broke over at 8 weeks old and haven't budged since,even when teething.
Tylers were a little later breaking but again they stayed put.

Both of mine are off parents which have good tidy ears though which helps.

That what i thought was strange both her parents had tidy ears as well, but tTia stick up but thats what makes her so lovely, i have photos of her in the gallery.

The trouble is you don't really know what breeding is behind her or if anything else has been added into to her lineage.

I thought staffies ears are ment to be down-my stellas ears went down when she was about 10 weeks

They are supposed to look like this,



Stick up ears or full drop etc are considered faults.

Ive seen quiet a few with their ears up even someone on here, on the bottom of threads. some times she has 1 up and 1 down lol, and sometimes both down, if she relaxes they stay down.

How old is Tia now?

Tia is 2 now, Here is a pic when she was a pup her ears were fine lol.

My stella does have ears like this not seen a adult staffie with ears sticking up- is it from poor breeding ?
