The official answer from
FCI (20.10.06)
Dear Mrs. Kuehnel,
Please find hereunder the official letter
(and our translation) from the Federacion
Canofila Mexicana concerning the
crossing between Chihuahuenos long coated and smooth coated.
"Le informo que actualmente la Federacion Canofila
Mexicana NO ACEPTA la cruza entre ambas varieades.
Incluso le recuerdo que por este motivo se otorga un CACIB a cada
variedad."
Translation:
"We inform you that in the present time the
Federacion Canofila Mexicana DOES NOT ACCEPT the crossing between
both varieties. That's the reason why the CACIB is attributed
to each variety."
Yours sincerely
The FCI Secretariat
