could somebody please let me know if my uncle can show his shih tzu the thing is he has him clipped? i was told it was un acceptable and he is wasting his time

Nothing to stop him showing him, but with one of his main features (the coat) missing he isn't going to get anywhere.  If her were to let his coat grow it might take a year or more for it to be the correct texture again if ever.

He can't be stopped from showing but if it was at an Open show, limit show or Championship show the dog wouldn't be placed and it wouldn't be worth paying out to show it.

He could of course show it at companionship shows.

Just to play devils advocate, and go in a completely different direction as to why he wants to show.  IF he is just starting out, and appreciates that he is unlikely to be placed abouve dogs in full coat, but wants the experience and practice at Open shows, then go ahead.  And if the dog should happen to be a really outstanding specimen, who knows, he may even get a place or two.  At least he will get some experience in the ring.  Cut down coated breeds can win, but it is rare, and then only exceptional dogs (Ambrose won a CC under an American breed specialist a few years ago, sporting a very smart "puppy" trim, and Choice won RCC at Crufts in a half coat).  Going to the other end of the scale, I am taking to Yankees in Pet trim to an open show next weekend, simply to keep the numbers up.  Both dogs will enjoy a day out, and neither will have the faintest idea that they are standing at the wrong end of the line!

the breed open shows ha ve classes for clipped dogs and bitches...if he wants to show then by all means go to one of these first...shihtzu are supposed to be in full coat when in conformation classes at open and championship shows the breed clubs have asked special permission for clipped nutered dogs to be shown at their open shows....the next one is wales and western shihtzu club show held at usk in wales or there is the shihtzu club christmas show and various others ....for information on these shows please get your uncle to phone the secretaries of manchu..shihtzu..wales and western..northern shihtzu clubs.....

thank you all for your advice i will try and tell him
take care
