I think someone is fibbing to you Richard.
Cute little guys though.
I don't doubt that... When we talked with the family surrendering the pups, they told us that they were females... We were gong to name them Ruby and Roxie, they turned out to be Ruben and Rocky
However, I have seen litters that were born in our home that included very different looking dogs like this. If a female is bred by several males over the period of her heat, you can have a litter of puppies sired by multiple fathers of multiple breeds...
Nicely done, Ruben looks too glamorous.
Right you are John, Ruben is the more sedate and glamorous of the pair while Rocky is a bit scruffy but, is more lively and fun loving...
they look like so, Richard. Rocky will be the dominant of the pair...
I think you're right.
Same mother possibly, but definitely different fathers.
