If it's a minor injury rather than a serious defect, I'm going to ask for the O.K. to breed her when she's bigger. Injuries aren't genetic, right?
If it is in fact an injury (how can you prove it is?), then no, it isn't genetic. However, no one can say with 100% certainty that it is or isn't genetic unless LLL admits to closing her tail in a deli cup, which then IMO you would be entitled to a refund.
