Barrows and Phillips: Color in Cocker Spaniels 



393 



CHAMPION SCIOTO PHILIP 



Red and white Cocker Spaniel owned by Dr. J. McI. Phillips; his formula is known to be Be 

 be, and he also carries the bicolor factor. Mated with a black female of pure ancestry, 

 all the pups will be black; mated with a red female of pure ancestry, all the pups will be 

 red; while if the mating is with a female that likewise carries the bicolor factor, all the 

 pups will be bicolor. Results of the mating can be predicted with fair accuracy in the 

 case of a mating v/ith any other type of Cocker Spaniel. (Fig. 4.) 



This single pedigree is mentioned to 

 show that dilute colors do occur, and 

 that the dilution factor is a recessive 

 and becomes visible only occasionally 

 or as a result of inbreeding in a strain 

 which carries it. It seems improbable 

 that the whites mentioned are true 

 albinos. We are inchned to consider 

 them as dilute lemon. Dilute reds are 

 cream in color. The photograph of 

 Simcoe Purity shows a slight darkening 

 which might be due to yellow, invisible 

 to the eye, but accentuated by the 

 photographic plate. 



ROAN PATTERN 



A mixture of white hairs with the 

 normally colored ones gives rise to the 

 roan colors, of which our records show 

 two litters. In the first a blue roan 



(black with white hairs) mated with a 

 red spotted gave three black and white 

 pups and two red roans, in the second 

 another blue roan mated with red 

 spotted gave three blue roans, and one 

 liver roan. This is probably a 3 by 8 

 mating, the roan animal being homo- 

 zygous for the roan factor. The roan 

 pattern factor is evidently dominant. 



SPOTTING 



Spotting occurs in two general types, 

 which we shall speak of as ordinary 

 spotting and bicolor spotting. The 

 ordinary spotting is the common condi- 

 tion in which the dog is more or less 

 irregularly marked with patches of 

 black and white, red and white, lemon 

 and white, or liver and white. The 

 spots vary from small breast or face
