  • Growing Interest in Hormone Sparing Dog Sterilization and Recommendations for Standard Identification Methods Linda Brent Parsemus Foundation, San Francisco, CA
    Growing interest in hormone sparing dog sterilization and recommendations for standard identification methods Linda Brent Parsemus Foundation, San Francisco, CA Abstract Sterilization methods for pets have been around for more than a century, but the practice of spaying and neutering dogs varies globally, from being considered a standard of responsible care in some countries to an infringement of animal welfare in others. In the US, advocacy for spay/neuter programs became widespread in the 1970s to address canine overpopulation. More recently, research on the impact of canine neutering has identified potentially serious health and behavior consequences of removal of the gonads and associated sex hormones that appear to be influenced by sex, breed, age and environment. An alternative is hormone preserving sterilization, including hysterectomy and vasectomy, which allows population control while maintaining natural hormone concentrations. Informal analyses regarding alternatives to traditional spay/neuter indicate that interest from the public and veterinarians has grown in the last 2 years, public demand for veterinarians who offer alternatives is increasing and although most veterinarians acknowledge the pros and cons of gonadectomy, the number providing hormone preserving sterilization is very low. Given current trends toward individualized medicine and increasing public demand, it is likely that the number of practitioners who offer vasectomy, hysterectomy or other hormone reserving sterilization procedures will grow. Now is the time to develop standard methods of identifying dogs who have received such procedures, so that they do not unnecessarily undergo a second surgery. Following an analysis of current practice and available identification methods, we recommend that simple green tattoos be applied to the inguinal area (“X” for hysterectomy and “V” for vasectomy) to identify sterilized dogs.

  • Canine Reproductive Disorders
    Vet Times The website for the veterinary profession https://www.vettimes.co.uk Canine reproductive disorders Author : Jennifer Cartwright Categories : RVNs Date : November 1, 2011 Jennifer Cartwright RVN A1, discusses the variety of issues that can lead an owner to ask if their pet should be neutered Summary INpractice, while running our nurse clinics, we are often asked about the benefits of neutering. This is something a nurse should feel confident speaking about, as this will give clients faith in your knowledge and confidence in your practice. It is very stressful for clients to leave their pet with the practice, but if they trust you it makes the experience a little easier for them. This article aims to recap and revise common reproductive disorders in the dog and provide the reader with a better understanding when answering the “should I neuter my dog?” question. For ease of reading, the article is separated into female and male conditions. Key words neutering, reproduction, prevention, hormonal, congenital Conditions affecting female dogs Follicular cysts This condition is most common in older bitches that have previously had normal seasons. • Symptoms. The bitch will tend to have a longer pro-oestrus and a thickened vulval discharge for 1 / 7 approximately four weeks afterwards. The season tends to cease due to the lack of luteinising hormone. • Diagnosis. Ultrasound is useful, as it will show larger follicles, such as cystic follicles. Cytology of the vagina may be useful, as it will show cornified cells that will not alter at late pro-oestrus. Usually, these cells would not be visible at this stage in the cycle.

  • Castration Or Neutering
    CASTRATION OR NEUTERING What is meant by castration or neutering? Neutering and castration are the common terms used to describe the surgical procedure known scientifically as orchidectomy or orchiectomy. In this procedure, both testicles are removed in order to sterilize a male cat. Why should I have my cat neutered? Neutering is very beneficial to the health of the cat, especially if performed at an early age. Following puberty, which occurs at approximately eight to nine months of age, the male cat often develops a number of undesirable behavioral changes. He will become territorial and start to mark areas, even inside the house, by spraying urine. This urine has a particularly offensive odor and is difficult to remove. As the tomcat reaches sexual maturity, he will start to enlarge his territory, straying ever farther from the house, particularly at night. It is for this reason that many of the cats that are hit by automobiles are non-neutered males. By increasing the size of his territory, he increases the likelihood that he will come into contact with other cats and will get into fights for territorial dominance. Inflicted fight wounds can result in severe infections and abscesses. Diseases such as FIV and FeLV, which can cause AIDS-like syndromes and cancers in cats, are spread through cat bites, these cats are most commonly affected by such incurable diseases. Last, but not least, neutering prevents unwanted litters and the needless deaths of tens of millions kittens and cats each year. The longer a tomcat sprays and fights, the less likely neutering will stop these behaviors.

Under very specific circumstances these can be valid considerations. What they do not like to tell you is that neutering will only have an effect on dominance and aggression if it is done between 6 and 9 months of age.

  • The Case for Neutering at Five Months of Age Richard Speck, DVM Animal Protective League, Springfield, Illinois
    PRACTICE TO PRACTICE THE CASE FOR NEUTERING AT FIVE MOntHS OF AGE Richard Speck, DVM Animal Protective League, Springfield, Illinois graduated from veterinary school in 1982. As I look back, I don’t recall hearing the words “pet Ioverpopulation” or “shelter medicine,” which is likely because I was not listening. Most of us were zeroed in on pharmacology, pathology, physiology, and dermatology—and bracketology during March Madness. As I entered practice, I was informed that the local humane society was overrepresented with irrational people who did not pay their bills. I agreed to a re- quest by the new humane society president to teach two of their veterinary assistants how to draw blood from cats, and I also began to see the world from a somewhat different perspective. I saw that the tears shed for injured, abused, and homeless animals were not, for the most part, from crazy people, but rather from normal dedicated, hard-working, caring individuals. They did their best without many supplies, no room to spare for animal housing, and little money. As I gradually became more involved with the local humane society, I realized that no matter how many unwanted pets were given to good homes, the supply of new homeless pets was continually overwhelming. As a result of this hopeless situation, my specialty be- came pet population control, specifically neutering.

  • Neutering and Contraception Methods for Ferrets
    Neutering and contraception methods for ferrets RSPCA COMPANION ANIMALS PET CARE FACTSHEET Female ferrets, or jills, are induced ovulators, (i.e. they require the act of mating to stimulate them to release an egg for fertilization). This means that they will stay in season (or oestrus) until they are mated, or until day length shortens.1 Remaining in season can cause often severe health problems for a jill; including alopecia (hair loss) and even death from oestrogen-associated anaemia (deficiency in red blood cells).2 Methods to manage a jill’s reproductive biology to prevent such health issues may be either surgical (neutering), chemical (contraception) or a combination of both. Some owners may use vasectomised hobs to bring their jills out of season through the act of mating. All options also prevent unwanted pregnancy and can help reduce aggressive behaviour and the typical musky smell associated with the maturing male (or hob). There are benefits and risks to each method and this document aims to provide information for ferret owners to use in discussion with their vet, to decide which method is best for their pet. SURGICAL NEUTERING - CASTRATION AND SPAYING • Spaying is the term for the surgical removal of the ovaries and uterus. Castration involves the surgical removal of the testes; a castrated male is known as a hobble. • Castrating hobs can reduce aggressive behaviour and increase play 3, both in surgically neutered animals and those receiving contraceptive treatment (see below). • Castration is generally also a cheaper option than chemical contraceptive methods. • However, surgical neutering in ferrets of both sexes has been linked with the occurrence of hyperadrenocorticism (adrenal disease), and adrenal tumours.4 • Research suggests that this is caused by excessive production of sex hormones following neutering.5 • Signs of hyperadrenocorticism in ferrets include some that are similar to prolonged oestrus in jills (e.g.

  • Why Should I Spay Or Neuter My Pet?
    WHY SHOULD I SPAY OR NEUTER MY PET? The City of Millville is concerned about the number of homeless animals who are abandoned or surrendered to shelters and wants to bring you this information about protecting your pet’s health and preventing the birth of more kittens and puppies. Annually in the U.S., there are an estimated 6-8 million homeless animals entering animal shelters and more than 2.7 million healthy, adoptable cats and dogs euthanized in shelters. Spaying females and neutering males is the only permanent, 100 percent effective method of birth control for dogs and cats. Besides spaying and neutering being the right thing to do to prevent unwanted puppies and kittens, these procedures also have important health benefits for your pet. According to a report in USA Today (May 7, 2013), neutered and spayed dogs live longer than intact dogs. There is a similar disparity in lifespans among cats. Spayed and neutered pets are less susceptible to certain infections and cannot contract uterine, ovarian or testicular cancer. Another reason for this longer life span is that spaying and neutering reduce your pets drive to roam in search of a mate. Roaming can lead to cats and dogs being lost or injured by vehicles or in fights with other animals. If they wander, they are also more likely to pick up parasites. Spaying or neutering your dog or cat will reduce some undesirable behaviors. Besides roaming, unaltered dogs and cats, especially males, urine mark their territory. Excessive barking, mounting people and other animals and other dominance establishing behaviors are also greatly reduced among spayed and neutered dogs.

  • The Age at Which Dogs Reach Sexually Maturity Depends to a Certain Extent Upon Their Sex and Breed
    The age at which dogs reach sexually maturity depends to a certain extent upon their sex and breed. Male dogs can become sexually mature from 5 months of age. Bitches usually have their first season between 6 and 12 months of age although toy breeds may come into season slightly earlier and giant breeds may have their first season as late as 18-24 months of age. There is no defined age at which we would recommend neutering. It is done on a case by case basis. For example, if an adolescent male is developing behavioural problems, he can be castrated as early as 6 months of age. In bitches we recommend timing neutering to 3 months after the end of a season. This is to reduce the likelihood of a phantom pregnancy or her return to season. The younger a bitch is neutered the less likely she is to develop mammary masses later in life. Some bitches can be neutered prior to the first season, although this may not be appropriate for each case. These cases should be discussed with your vet. The surgery is carried out under general anaesthetic. This is understandably a worry for some clients; however every step is taken by your vet to reduce any potential risks. Prior to any surgery we advise you bring your dog to the vet for a general health check. The night before surgery we recommend taking food away from midnight; however access to water should be maintained. When your dog is admitted for surgery, after a health check, they receive a premedication containing pain relief and a sedative.

  • Spay and Neuter Q&A the Truth About Spaying Or Neutering Your
    Spay and Neuter Q&A The Truth About Spaying or Neutering Your Cat By Sandy Eckstein FROM THE WEBMD ARCHIVES An estimated 5 million to 8 million animals are euthanized in shelters across this country every year. Many organizations are working to decrease that number by opening low-cost spay/neuter clinics that will prevent more litters of cats that need homes. One such organization is LifeLine Animal Project, an Atlanta-based nonprofit shelter and clinic where more than 25,000 spaying and neutering procedures have been performed since 2005. Here, executive director Rebecca Guinn answers the most commonly asked questions about spaying and neutering cats. Q: Why should I have my cat spayed or neutered? A: Shelter euthanasia is the number one killer of companion animals. Spaying and neutering is the only way to reduce or eliminate that. It’s also better for your pet’s health. And having a cat that’s spayed or neutered will make your life easier. Q: Shouldn’t I let my cat have a litter before I spay her? A: No. It greatly reduces the risk of certain cancers if you have her spayed before the first heat and certainly before she has a litter. Most places are overrun with kittens. There are millions of cats and kittens that need homes and millions more that are abandoned. There simply aren’t enough homes for all the cats that get born every kitten season. Q: Should I let my cat have a heat before I spay her? A: It’s a myth that animals should have a litter or a heat before they are spayed.

  • Spaying Or Neutering
    Spaying or Neutering How will spaying or neutering affect my pet? Spaying a female pet involves removing the ovaries and uterus. This procedure will eliminate the heat cycle. o Dogs are in heat for about 21 days twice a year; cats are less predictable, but can be in heat 3-15 days, 3 or more times a year o Male dogs can be drawn from blocks around by the scent of a female in heat – even when she’s kept indoors. o Dogs in heat will produce a bloody discharge, which can stain furniture. o Cats in heat may pace nervously and cry or yowl. o Pets in heat may frantically try to get outside in an effort to find a mate. Neutering a male pet involves removing the testicles, which produce the hormone testosterone. o Male cats left in tacked tend to mark their territory with foul smelling urine. Once this habit is established, neutering may not eliminate a learned behavior. o Non-neutered male pets tend to have an urge to roam in search of a mate. o Non-neutered male pets tend to mount furniture, cushions, and people’s legs when frustrated. o Non-neutered male pets tend to be more aggressive and therefore are more likely to be involved in bites or injured in fights with other animals. Why should I consider spaying or neutering my pet? There are many health benefits to spaying your pet. o Almost 50% of unspayed dogs develop breast tumors. Virtually none do if spayed before their first heat, and chances are reduced if spayed thereafter.
