Goats, sheep, cows, pigs, rabbits, mules, horses, deer, cats and mice have been cloned for commercial and biomedical purposes. In August, 2005, the first dog was cloned, an Afghan hound, by South Korean researchers at Seoul National University where earlier, human embryos had been cloned and stem cells extracted. The surrogate mother of this cloned dog was a yellow Labrador retriever. One hundred and twenty three dogs were used as both egg donors and surrogate mothers, and from over 1,000 prepared eggs or ova each containing a skin cell from a dog’s ear, three pregnancies resulted, one ending in a miscarriage, one resulting in a pup that died soon after birth from respiratory failure, and the third a viable clone of a male Afghan hound. Some bioethicists fear that the cloning of man’s best friend is the final stepping stone to eventual public acceptance of human cloning.
Cloning entails taking a single cell from an animal and placing the cell inside the egg case or ovum taken from another animal of the same species, that has been emptied of its contents. After a procedure that activates the cell to begin to divide, the ovum containing the cloning cell is placed in the uterus of a hormonally receptive surrogate animal. Because of low success rates in getting the cloned cells to implant into the uterine wall, and because the placenta and embryo may not develop normally, several ova containing the clone cells may be put into the surrogate animal’s uterus at the same time.
People taking a beloved dog or cat to the veterinarian for a routine health check will have a few cells removed, quickly frozen, and shipped for storage at a Pet Cloning Center. A processing and storage fee will be charged, and when the owners want their companion animals to be cloned, the Center will begin the process after a substantial down payment has been made, or full payment has been provided. Before this new biotechnology is perfected and large-scale operations set up with hundreds, possibly thousands, of caged and hormonally manipulated female dogs and cats serving as ova donors, and others being the recipients of ova containing the to-be-cloned pets’ cells, the cost will probably be in the six-figure range for some time before mass-production follows mass-demand. But there are many concerns other than financial:
The cloned dogs will not be exact replicas of peoples’ beloved animal companions, and many clones will probably be spontaneously aborted, or have to be destroyed because of various birth defects. Abnormalities may also develop later in life. Clones of other species often have abnormal internal organs, neurological and immunological problems, and may be abnormally large at birth due to a defective growth-regulating gene function. What about the origins, quality of life and future of the thousands of caged female dogs who will be exploited by the pet cloning industry, and the procedural risks to their health and overall welfare?
Do the ends justify the means? There is no evident benefit to the animals themselves.
Why not adopt from an animal shelter a dog or puppy who looks like the one you miss or might be passing on soon, who needs a good home; or donate money, equivalent to what it would cost to produce one clone, toward improving the welfare of hundreds, even thousands of dogs, and other animals in communities around the world?
What are these ends anyway? Certainly there is a commercial end that is potentially lucrative, given the right market promotion and endorsements by professionals and celebrities.
But is there real human benefit in making a clone of one’s beloved canine companion? Or is it mere pandering to a misguided sentimentalism? Because of the close emotional bond between humans and their animal companions, the pet cloning business I see as an unethical exploitation of the bond for pecuniary ends. Exact replicas of peoples’ dogs cannot be guaranteed, and will not likely be created because an identical environment during embryonic and postnatal development cannot be achieved. All clones may, at the time of birth, be of the same chronological age as the age of the cells taken from the to-be cloned animals. So if a cell is taken from a six-year-old dog, because of the aging “clock”, the clone may already be aged by six years at the time it is born.
From various religious and spiritual perspectives and beliefs, cloning violates the sanctity of life and the integrity of divine or natural creative processes. It is problematic from the point of view of reincarnation, or transmigration of the soul. From a Buddhist perspective, the consciousness incarnate in the body of the clone, or the consciousnesses in the bodies of many clones from the same original animal, are all going to be different from the original donor.
It is not inconceivable that dog clones might also be created initially on an experimental basis, and used to provide spare parts such as kidneys, hearts, hips, and knees for ailing dogs. Research laboratories may also use cloning to quickly develop identical sets of dogs and other animals for biomedical research. Some sets and lines of clones having the same genetically engineered anomalies to serve as high fidelity models of various human diseases may be created and marketed to develop new and profitable drugs to treat these conditions in humans and other animals.
The bioethics and medical validity of these developments need to be examined. And pet owners who put out the money to have their animal companions cloned may want to think twice, since they may well be giving this new cloning business not only a financial jump start, but also the socio-political credibility that it needs in order to gain widespread public acceptance, and a market for human cloning and for other biologically anomalous and ethically dubious products and processes.
The fact that a venture capitalist made a grant of $2.3 million and hired an agent to find a university biotech. laboratory already in the cloning business to clone his dog Missy (visit www.missyplicity.com ) and the subsequent public relations and media promotion of this project, points to another agenda: The cloning of pets may be a ploy to promote human cloning. If the cloning of pets becomes a reality, the public will become desensitized to the issue of cloning and more likely to eventually accept a highly lucrative biotechnology for childless couples and rich and selfish singles for the cloning of complete human beings, and of partial human beings (such as anencephalics or headless clones) as a source of replacement tissues and organ parts.
The Philosophy Department at Texas A&M University, where the Missyplicity Project was started in another department before being spun off into a private company “Genetics, Savings and Clone” developed a set of “bioethical guidelines” based on the ethical principle of what they call axiomatic anthropocentrism. This strategy was clearly designed to deflect public criticism and concern over the morality and animal welfare aspects of the Project. Axiomatic anthropocentrism essentially means whatever is good for people is ethically acceptable. Anthropocentrism — human centeredness — is an outmoded worldview or paradigm that many advocates of animal rights and environmental protection see as the root cause of untold animal suffering and ecological devastation over the millennia.
Several female dogs were put up for adoption on the web site, one of the company’s “bioethical principles” being that regardless of the source through which dogs are obtained for use as egg donors or surrogate mothers,( from animal shelters, breeding, farms, etc), at the completion of their role in the Missyplicity Project, all dogs shall be placed in loving homes. No funds shall be expended for dogs raised under inhumane conditions, such as puppy mills.
The Missyplicity Project included several goals in addition to the cloning of Missy that were published on the web site. These included dozens, perhaps hundreds, of scientific papers on canine reproductive physiology; enhanced reproduction and repopulation of endangered wild canids; plans to develop improved canine contraceptive and sterilization methods as a way of preventing the millions of unwanted dogs who are euthanized in America every year; to clone exceptional dogs of high societal value, especially search-and-rescue dogs; and develop low-cost commercial dog-cloning services for the general public.
These goals gave the Project the kind of credibility that a gullible public and organizations and professionals with a limited grasp of the inherent limitations and harmful consequences of cloning, would readily accept. Ethical concerns and the questions concerning the validity and relevance of applying cloning biotechnology to wildlife conservation, to dog overpopulation, and to the propagation of high performance dogs were cleverly deflected by these promissory goals.
Genetic Savings and Clone, the commercial spin-off from the Missyplicity Project at Texas A&M University, launched “Operation CopyCat” in 2000. The companyestimated that the price for cloning a cat or dog would drop to $25,000 withinthree years. They never succeeded in cloning a dog, and eventually out of business,but a northern California biotech company, BioArts International created severalcloned cats for sale at $ 50,000 each that turned out to be a commercial flop.Undaunted, BioArts linked with the disgraced* cloning scientist Hwang Woo Sukwho had succeeded in cloning dogs in Korea, in an effort to market cloned dogs inthe US in 2008. BioArts International set up a public auction to clone five dogs forwilling customers, with bids starting at $100,000! In another publicity stunt, thiscompany offered owners a free chance to have their dogs cloned, and chose theGerman shepherd rescue dog who worked in the rubble of the 9⁄11 terrorist attack at the World Trade Center in New York city, as the ‘most clone-worthy canine’.
UPDATE Nov 2018
As of 2018, Cedar Park, Texas-based ViaGen Pet& Equine Co. has been cloning horses and livestock for 17 years. The company began cloning pet dogs and cats in 2015. It is purportedly only company in the world that is cloning cats for pet owners and the only company in the United States that is cloning pet dogs. The company has also cloned cattle, pigs, sheep, goats, and white-tailed deer.
ViaGen Pets’ fee to the client for genetic preservation is $1600, with an annual storage fee of $150 after the first year. In addition, veterinary practices charge the client for their expertise in collecting the biopsy samples. Beyond these initial charges, cloning a dog costs $50,000; a cat, $25,000; and a horse, $85,000. There are a few hundred cloned dogs around now and there is a wait list. The current wait list to start the cloning process in dogs is about 2 months. For cats, the wait list is about 6 months.
Alice Villalobos, DVM, former president of the Society for Veterinary Medical Ethics and a pioneer in the field of cancer care for companion animals, looks favorably on the prospects of pet cloning: “As a veterinary oncologist also focused on palliative care and hospice for dogs and cats, I see how this could become a more accessible opportunity for those who want to have an option for a continuum with a genetically similar pet who they are on the verge of losing. I’ve had cloned dogs as patients and the owners are very happy with their decision,” said the California veterinarian.
John Woestendiek, a Pulitzer prize–winning investigative reporter and author of Dog, Inc.: The Uncanny Inside Story of Cloning Man’s Best Friend, has some negative opinions about pet cloning. In an interview with Scientific American, Woestendiek said, “An argument can be made that dog cloning is not only adding to the dog overpopulation problem, but causing a lot of pain and suffering along the way.”4 He views cloning “as an insult to the original dog—the equivalent of saying ‘I can easily (assuming I am wealthy enough) have another you created.’ The fact is you can’t. And it seems unfair to the clone as well, in terms of the expectations the dog owner will likely have for it.”
As to the ethics of veterinarians in pet cloning, James A. Serpell, PhD, professor of Animal Ethics & Welfare at the School of Veterinary Medicine at the University of Pennsylvania calls for people to be informed and to think twice.The most serious issue, according to Dr. Serpell, is when “people are made to believe that the animal they get back will be a replica of the original pet. That’s a huge mistake. They may be genetically identical, but a lot can happen after conception. It’s classic nature versus nurture, and with dogs and cats an awful lot is nurture.”
Cloning may help save endangered species but all to what pathetic end but another step toward virtual reality devoid of virtue by virtue of morally inverted, self-serving values and actions.

The objective of the present study was to investigate whether nuclear transfer of postmortem wolf somatic cells into enucleated dog oocytes, is a feasible method to produce a cloned wolf. In vivo-matured oocytes (from domestic dogs) were enucleated and fused with somatic cells derived from culture of tissue obtained from a male gray wolf 6h after death. The reconstructed embryos were activated and transferred into the oviducts of naturally synchronous domestic bitches. Overall, 372 reconstructed embryos were transferred to 17 recipient dogs; four recipients (23.5%) were confirmed pregnant (ultrasonographically) 23-25 d after embryo transfer. One recipient spontaneously delivered two dead pups and three recipients delivered, by cesarean section, four cloned wolf pups, weighing 450, 190, 300, and 490g, respectively. The pup that weighed 190g died within 12h after birth. The six cloned wolf pups were genetically identical to the donor wolf, and their mitochondrial DNA originated from the oocyte donors. The three live wolf pups had a normal wolf karyotype (78, XY), and the amount of telomeric DNA, assessed by quantitative fluorescence in situ hybridization, was similar to, or lower than, that of the nuclear donor. In conclusion, the present study demonstrated the successful cloning of an endangered male gray wolf via interspecies transfer of somatic cells, isolated postmortem from a wolf, and transferred into enucleated dog oocytes. Therefore, somatic cell nuclear transfer has potential for preservation of canine species in extreme situations, including sudden death.
