That is amazing. 5 generations and only one chocolate. I am impressed.
They all sound like wonderful babies. It’s definately hard to go to another breed once you have bitten by the Siamese bug. LOL
It's probably wise to keep those bloodlines separate -- just like keeping the Chocolate Labs out of your Yellow Lab bloodlines because of the risk of coming up with a "Dudley" (a Chocolate Lab with the dilute coat color gene that produces a Yellow Lab from a Black Lab. A "Dudley" is a Chocolate Lab with a yellow coat -- they have pink eye rims and a pink nose. Not a good thing for anybody, they're supposed to be more susceptible to sunburn and skin cancer, and disqualifying in the show ring).
