3) SOME GENERAL AND BREED SPECIFIC PRINCIPLES
In general it should be possible to cross CLOSELY RELATED BREEDS or BREED VARIETIES in order to
avoid or reduce health problems or problems caused by unhealthy construction. However please
note:
SIZE: Only breed to nearest variety in size – or risk of whelping problems.
LONG COAT: Long coat to long coat will always give long coat (as a single recessive gene).
COLOUR: Never breed Merle to Merle – ¼ will be homozygote for lethal/health defects, such as
deafness.

CANICHE (172): Avoid breeding grey (silver) to apricot or red – or risk of untypical colours.
