I also have a blue & gold yorkie and his name is sami too

The breeder I bought him from told me that they are called blue because his skin is almost colbalt or a blue black? the gold on sami looks like an amber so Im not sure what the differnce is other than I know sami has dark blue skin and actualy I would say he is blue black? your baby is too cute!! does anyone have any pics of the of the difference between blue & gold /blue & tan I know the tan is quite obvious but how does the breeder decipher the difference? here is a pic of sami and he is 9 months and he is still quite black his amber is turning into a blond looks like I had his hair weaved
