Often get an entry with a letter giving consent for the person who has entered the dog to do so - simple, one off letter that can be photocopied and sent with the entry.
The say something like:
We the undersigned give full permission for *********** to enter ************ in any show during 2010, to handle and to sign the entry form on our behalf.
The names of the owners are then typed and each signs.
Some do not put a date but I would advise that they do so they still have control over the dog - not so important if the dog is owned by husband and wife, a partnership or family member.
