Not for Competition rules at UK Kennel Club Breed shows
As of 2014
There has been much confusion in recent years of how old a puppy can be to enter Not for Competition at a UK Kennel Club Breed (conformation) show.
You can enter pups from 4 months NFC at single breed and sub group shows ONLY – all other shows (group and all breed) the NFC is from 6 months.
Some shows will allow spectator dogs and these can be of any age, there will often be a charge for this and you will need to see the secretary at the start of the show to fill a form in and pay (if the society are charging). This is open to spectators and not exhibitors technically
Rule F.1(c) states:
Only dogs of six calendar months of age and over on the first day of the Show are eligible for exhibition at Kennel Club licensed Shows.
However, societies may accept Not for Competition entries at their discretion. Dogs aged four calendar months and over are eligible to enter not for competition at Single Breed and Sub-Group Shows.
Furthermore, dogs aged four calendar months and over are eligible to enter Match competitions.
F(1) 11 states:
Animals Allowed in Show.
No animal other than an exhibit shall be brought into the precincts of a Dog Show during its continuance, except any dogs registered to assist the disabled, those brought for health testing (provided that the appropriate entry form declaration has been signed) or dogs required for educational or instructional purposes or by permission of the General Committee.However, at the discretion of the show society, a dog brought to the show by a spectator may be admitted into the precincts of the dog show, with the proviso that those in charge of the dog sign a declaration confirming the dog is free from disease and that the dog will be kept under proper control at all times. In the case of General and Group Championship Shows,the show society must apply to the General Committee for permission to admit spectators’ dogs as described above, and the granting of such permission will be entirely at the Committee’s discretion.
I hope this helps clear the NFC rule up for you.
