Both the sire and the dam must be at least 18 months old at the time of whelping.
The breeding shall not be the third or more back-to-back breeding for a bitch (if breedings are less than 10 months apart).
Litters will be listed for breeders. The breeder is defined as the owner of the litter, and is the owner or lessee of the dam of the litter. For the purposes of litter listings, ownership of the dam may be established by registration records or according to the criteria in Section 5.1 of the ESC Registry Rules and Regulations. Any suitable documentation may establish the breeder as the lessee of the dam.
