There are innumerable joys that come from sharing one’s life with a companion animal. As a result, many humans treasure their relationships with their dogs and cats. Indeed, for many humans, their relationship with their companion animal is one of the most rewarding relationships in their life. But despite the great value that we attribute to these relationships, we should not lose sight of the important arguments against breeding more companion animals.
Two of the arguments that we have considered—the anti-natalist and the abolitionist arguments—are categorically opposed to all breeding of companion animals. The harm prevention argument, on the other hand, is a conditional one (except in the case of “thoroughbreds”). According to this argument, until such time as the demand for companion animals exceeds the number of these animals already in existence, we should desist from breeding more of these animals and from allowing them to reproduce with one another, even though we should also care for those companion animals who already exist. However, given how many millions of unwanted animals there currently are, we are nowhere near that point. Thus, as things stand, all three arguments converge on the conclusion that reproducing companion animals is wrong. The case against breeding companion animals is significantly overdetermined.33
