> <br />Just one more questions - if they have not won their way out of Limit by the age of 7 would you keep them in in or move them to another class (or retire them)?<br />
To be honest, whether you keep at it would probably depend on WHY you show (if just for a day out, fine) and how deep your pocket is and whether you have a thick skin and don't mind continually (?) 'coming out with the rubbish'

. I heard one exhibitor, who managed to put a title on one of his 2 hounds, saying it had cost him a four-figure sum to campaign him to his title. On the other hand, my bitch, who came back to the UK with us from Canada, made her title in 3 straight shows!! Bit rare that I have to say but she did.
Again whether you move your dog does depend on (finances apart) how he is physically when compared to others in Limit. And whether most judges in your breed, look to the Open class, or to some flashy 'flier' puppy to give a major award to. I think with judges in the UK mainly being breeders too, your dog may have reached the point that he's being over-looked because he doesn't win very often? Harsh, but could be true.
Personally if one of mine hadn't made it by 7, or wasn't doing any significant winning (it can be hard putting a title on a dog in the UK, in a lot of numerous entry breeds) I'd retire them.
