Thankyou to everyone who replied to my question reguarding my irish setters underbite.  The answers confirmed what i already knew i suppose, but i still had a little bit of false hope that she may one day have a 'defect free' litter of pups.  I have no intention of breading her and thank you for your honest answers.  Lotti is nearly seven months now and her underbite worse than ever!  But she is a beautiful dog. Full of energy, with cheaky ways and she even answers me back!

Well done for making a responsible decision....there are too many people breeding dogs reguardless of their faults.
I'm sure you girl is beautiful in every other way and a super pet!!
