I'm glad to hear that someone has been able to breed a healthy dwarf. From what I have seen when people breed them they end up with chins with health issues and may not have very long lifespans. So, that is encouraging to hear!
Every now and then, like Kristy said, a breeder will end up with a dwarf. I always look at them as being runts and don't really pay much attention to them. Meaning that they go to a pet home and I ask about how they are doing. So far all the "runts" seem to be just fine and haven't had any bad issues that I know of, but I have heard other people say that they have had health issues with the dwarves.
This thread has been interesting to read, up until the point where people started getting angry at each other for assorted reasons. Exploring a new mutation for breeding is always challenging and a little scary. Differing opinions get people into heated discussion ...blah blah.
Tabitha - when Summer breeds the dwarves does she breed back to normal sized chins? Can this be considered to be somewhat like breeding for a recessive trait? Is it predictable?
