Well considering the genetics are complicated they are still a pretty rare type of rat in the pet trade. Most breeders don't even sell their tailess without them being first altered or spayed because there are so many complications in breeding them. Most does are spayed beforehand to prevent a possible terminal pregnancy. You can breed tailess carrier females to buck and also shorties (have a short tail) to tailess bucks.

I have a few more tailess carrier does and a new buck comming in December and hopefully I plan to begin breeding different types into the lines. My goal is a merle dumbo tailess. I had the first dumbo tailess ever born in Oregon.
