Mas o estalão não nos informa acerca desse assunto...

Desculpe discordar, mas se consultar o site da FCI e ler com atenção o estalão do English Cocker Spaniel irá encontrar o seguinte sobre as cores:
"COLOUR : Various. In self colours no white allowed except on chest."
Sem ser no peito, o branco não é permitido.
Se se refere ao American Cocker Spaniel:
"COLOUR AND MARKINGS :
• Black variety : Solid colour black, to include black with tan points. The black should be jet; shadings of brown or liver in the coat are not desirable. A small amount of white on the chest and/or throat is allowed; white in any other location shall disqualify.
• Any Solid Colour Other Than Black (ASCOB) : Any solid colour other than black, ranging from the lightest cream to darkest red, including brown and brown with tan points. The colour shall be of a uniform shade, but lighter colour of the feathering is permissible. A small amount of white on the chest and/or throat is allowed; white in any other location shall disqualify.
• Parti-Colour variety : Two or more solid, well broken colours, one of which must be white; black and white, red and white (the red may range from lightest cream to darkest red), brown and white, and roans, to include any such colour combination with tan points. It is preferable that the tan markings be located in the same pattern as for the tan points in the Black and ASCOB varieties. Roans are classified as Parti-Colours and may be of any of the usual roaning patterns. Primary colour which is ninety percent (90%) or more shall disqualify.
• Tan points : The colour of the tan may be from the lightest cream to the darkest red and is restricted to ten percent (10%) or less of the colour of the specimen; tan markings in excess of that amount shall disqualify. In the case of tan points in the Black or ASCOB variety, the markings shall be located as follows :
1) A clear tan spot over each eye;
2) On the sides of the muzzle and on the cheeks;
3) On the underside of the ears;
4) On all feet and/or legs;
5) Under the tail;
6) On the chest, optional : presence or absence
shall not be penalized.
Tan markings which are not readily visible or which amount only to traces, shall be penalized. Tan on the muzzle which extends upward, over and joins shall also be penalized. The absence of tan markings in the Black or ASCOB variety in any of the specified locations in any otherwise tan-pointed dog shall disqualify."
Se o cão for de variedade toda preta, o branco só é permitido no peito.
Se o cão tiver outra cor sólida para além de preto, só poderá ser de creme a ruivo, incluindo castanho, sendo uma pequena porção de branco permitido se for no peito ou garganta.
Existe outra variedade em que é permitido o branco mas apenas misturado com outra cor, tal como branco-preto, branco-ruivo, branco-castanho.
Penso que tem aqui a resposta à sua pergunta.
