If an animal as a female has a deformity, kinked tail or crooked spine, maybe as she grew she got masses forming on her (cancer?). Would this automatically exclude her from breeding, I should ask, should it because these are things that will be passed to her offspring? Or do deformity in an animal only effect said animal and the offspring would be fine? Do animals with a deformity make for an okay pet, but not an okay breeder because of the possible risks to the next generation? Just random stuff in my head I thought I would put out there. Would it depend on what the deformity is because some are no big deal (visual) and some would be an issue (life threatening)?
