The photos are fantastic, I love the Merle's, they are my favorite colour of all. I did a friend request on Facebook, hope you don't mind. Mostly in Australia spoodles are English cocker x mini...
more a buff/red dog with liver pigment (nose, eye rims, lips), would carry chocolate. I would guess that the same is true for Spoodles. As for eye color, I have no clue. ;)
Are you in Australia? I have not seen any blue Merles in OZ. sorry can't help with the genetic side of things. Do you have any photos of your puppies? Are you only breeding f2's?
