CHAMPION SCIOTO TAD POLE 



Black and white Cocker vSpaniel bitch owned by the Scioto Kennels (Dr. J. McI. Phillips). 

 Her formula has been ascertained to be BE Be, and reference tn the table published on 

 another page makes it easy to predict the results of mating her with any kind of dog of 

 the same breed, whose formula is likewise known. Black is a harder color to work with 

 than any other in Cocker vSpaniels, because research shows that there are four kinds of 

 black which look alike but breed differently. Furthermore, the presence of white (or 

 "spotting ") adds another complication, because it is apparently due to a number of separate 

 factors, which usually act as a unit. As the spotting is usually dominant, we can say at 

 a glance that the jnips of this l)itch will jirobably all he spotted, but whether they will 

 be black and white <jr red and white can only be predicted liy complete knowledge of the 

 genetic makeup of the dog with which she will he mated. (Fig. 3.) 



DILITK COLORS 



There occtirs oeeasionally amonj^ 

 Cockers a dilute color (dilute black), 

 known as blue, and also individuals 

 which appear to be white. Fij^. 6 

 shows Simcoc Purity, (jne of these 

 whites, owned by Frank E. Curtis. 

 Simcoc Purity was from a solid black 

 sire and a solid red dam. In the same 

 litter were two red females, Doris and 

 Betty. Mr. Curtis describes the pro- 

 ductions of whites and blues from these 



in these words: "I bred Purity to his 

 two litter sisters Doris and Betty and 

 never failed to tj;et one or two pure white 

 pups in every litter, and with one excep- 

 tion they were always strong and 

 healthy. I usually had in each litter 

 what mi}^ht be called a blue jnip (in my 

 opinion a miserable color) the others 

 were either red or black. When Purity 

 was in stud he was bred to outside 

 bitches, Init never threw a jiure white 

 jju])." "Purity's eyes, no.se, and foot 

 pads were black."
