Our contract states that you must agree to spay your female AFTER their first season and neuter the males at 2 years of age. We have seen the positive affects with our own golden retrievers who are not spayed or neutered
until after they have fully matured and the growth plates closed. We have also witnessed those puppy owners who decided to spay their females before or at 6 months and not follow our advice and therefore also voided our contract nullifying all guarantees.
Reports of incontinence for the rest of their lives and needing to be on Proin daily is disheartening. Waiting to spay/neuter helps lengthen their lives and avoid joint injuries. Please read the study specifically for golden retrievers conducted by UC

The UC Davis Golden Retriever Study on the effects of early Spay & Neutering, and the age at which a dog is neutered, may affect
the animal’s risk for developing certain cancers and joint diseases, according to a new study of golden retrievers by a team of researchers at the University of California, Davis.
The study, which examined the health records of 759 golden retrievers,
found a surprising doubling of hip dysplasia among male dogs neutered before one year of age. This and other results were published Feb. 13 in theonline scientific journal PLOS ONE.
study results indicate that dog owners and service-dog trainers should carefully consider when to have their male or female dogs neutered,” said lead investigator Benjamin Hart, a distinguished professor emeritus in the UC Davis School of Veterinary
“It is important to remember, however, that because different dog breeds have different vulnerabilities to various diseases, the effects of early and late neutering also may vary from breed to breed,” he said.
of the new study are revealing, Hart said the relationship between neutering and disease-risk remains a complex issue. For example, the increased incidence of joint diseases among early-neutered dogs is likely a combination of the effect of neutering on the
young dog’s growth plates as well as the increase in weight on the joints that is commonly seen in neutered dogs.
Dog owners in the United States are overwhelmingly choosing to neuter their dogs, in large part to prevent pet overpopulation or
avoid unwanted behaviors. In the U.S., surgical neutering — known as spaying in females — is usually done when the dog is less than one year old.
In Europe, however, neutering is generally avoided by owners and trainers and not promoted
by animal health authorities, Hart said.
During the past decade, some studies have indicated that neutering can have several adverse health effects for certain dog breeds. Those studies examined individual diseases using data drawn from one breed or
pooled from several breeds.
Against that backdrop, Hart and colleagues launched their study, using a single hospital database. The study was designed to examine the effects of neutering on the risks of several diseases in the same breed, distinguishing
between males and females and between early or late neutering and non-neutering.
The researchers chose to focus on the golden retriever because it is one of the most popular breeds in the U.S. and Europe and is vulnerable to various cancers and
joint disorders. The breed also is favored for work as a service dog.
The research team reviewed the records of female and male golden retrievers, ranging in age from 1 to 8 years, that had been examined at UC Davis’ William R. Pritchard Veterinary
Medical Teaching Hospital for two joint disorders and three cancers: hip dysplasia, cranial cruciate ligament tear, lymphosarcoma, hemangiosarcoma and mast cell tumor. The dogs were classified as intact (not neutered), neutered early (before 12 months age),
or neutered late (at or after 12 months age).
Joint disorders and cancers are of particular interest because neutering removes the male dog’s testes and the female’s ovaries, interrupting production of certain hormones that play key roles
in important body processes such as closure of bone growth plates, and regulation of the estrous cycle in female dogs.
The study revealed that, for all five diseases analyzed, the disease rates were significantly higher in both males and females that
were neutered either early or late compared with intact (non-neutered) dogs.
Specifically, early neutering was associated with an increase in the occurrence of hip dysplasia, cranial cruciate ligament tear and lymphosarcoma in males and of cranial cruciate
ligament tear in females. Late neutering was associated with the subsequent occurrence of mast cell tumors and hemangiosarcoma in females.
In most areas, the findings of this study were consistent with earlier studies, suggesting similar increases in
disease risks. The new study, however, was the first to specifically report an increased risk of late neutering for mast cell tumors and hemangiosarcoma.
Furthermore, the new study showed a surprising 100 percent increase, or doubling, of the incidence
of hip dysplasia among early-neutered males. Earlier studies had reported a 17 percent increase among all neutered dogs compared to all non-neutered dogs, indicating the importance of the new study in making gender and age-of-neutering comparisons.
