NEUTERING and HD and CANCER - Page 1

Another scientific study  of consequences of neutering and spaying and of why not to neuter your dog as a routine. If you read below you will see statistical consequences where HD  increased 3x in males who are neutered young and also significant increase of different cancers in males and females if spayed or neutered. .
 Thus anybody who is telling you that neutering is harmless is laying to you from ignorance or for financial gain. 

Quote from link below:
 In contrast to European countries, the overwhelming majority of dogs in the U.S. are neutered (including spaying), usually done before one year of age. Given the importance of
gonadal hormones in growth and development, this cultural contrast invites an analysis of the multiple organ systems that may be adversely affected by neutering. Using a single breed-specific dataset, the objective was to examine the variables of gender and age at the time of neutering versus leaving dogs gonadally intact, on all diseases occurring with sufficient frequency for statistical analyses. Given its popularity and vulnerability to various cancers and joint disorders, the Golden Retriever was chosen for this study. Veterinary hospital records of 759 client-owned, intact and neutered female and male dogs, 1–8 years old, were examined for diagnoses of hip dysplasia (HD), cranial cruciate ligament tear (CCL), lymphosarcoma (LSA), hemangiosarcoma (HSA), and mast cell tumor (MCT). Patients were classified as intact, or neutered early (<12 mo) or late (≥12 mo). Statistical analyses involved survival analyses and incidence rate comparisons. Outcomes at the 5 percent level of significance are reported.Of early-neutered males, 10 percent were diagnosed with HD, double the occurrence in intact males.

Almost 10 percent of early-neutered males were diagnosed with LSA, 3 times more than intact males. The percentage of HSA cases in late-neutered females (about 8 percent) was 4 times more than intact and early-neutered females. There were no cases of MCT in intact females, but the occurrence was nearly 6 percent in late-neutered female  The results have health implications for Golden Retriever companion and service dogs, and for oncologists using dogs as models of cancers that occur in humans.C

Sure wish they would do a study on German Shepherds too.

Sitasmom the results may be different in GSD but I doubt that they would.  

I am in agreement that environmental factors have a huge influence on puppy development and structural issues.  There is also research that hormones in the mothers milk can have influences on the puppies development ( The Dog and It's Genome ).  The dogs endocrine system and organs are influenced by the sexual hormones produced by the sex organs that get cut out with neutering.  Just like raw food and vaccines, many veterinarians give uninformed advice or advice that is weighted to maximize their profits.. 

As someone who had a golden die from cancer and the HUGE problems associated with the breed to getting cancer, not sure I would take heart with the link between the two with this breed. I would be more apt to pay attention if they picked a breed that isnt known for dying of cancer then link their findings to hd. The research I found was that an approximate 60% of goldens will get cancer in their lifetime. Too high for me to link the two.

I will say that had someone neutered this guy I have now, who is 10 and not neutered, then we wouldn't be having the prostate problems we are having that have bee directly linked to his jewels being kept.

BHaugh, that is an overall systemic problem; you can't say that keeping a body system that nature intended CAUSES problems. Environment, diet, genetics, etc. cause or influence the development of such problems.Having testicles is not the problem. Having a uterus in itself is not inherently dangerous. I can't say "Dammit, had I whacked off this problematic arm, I wouldn't be having these darn carpal tunnel problems."   We can't just remove everything that is prone to disease. Instead, we need to focus on creating overall healthier animals by genetics, environment, diet, etc. JMO. 

As you can see there is not much of statistical difference between Golden Labradors and GSD's. And Besides that is not the point ,. ....there is still the multiple of HD and( Cancer ) between neutered and not neutered dogs which  should be same. Mathematically it should not make a difference. ​

@ Jenni's post, removing problematic body parts seems to be the philosophy with dog owners for eons. Ears are chopped off guardians breeds, dew claws on the front feet are cut off the prevent injury on breeds that digging is a part of their work ( terriers, excavating a varmint's den), tails docked to prevent injury to them. All these body parts being removed are logical have have merit. But then whacking off testicles became vogue because, we are told, the dog we will die if he's allowed to keep them.....same thing with a bitch's uterus; leave it in and she dies...But at the same time, people are overfeeding their dogs causing obesity and the vets just treat the complications rather than tell the owner, your dog is TOO FAT.
