Spaying & Neutering Your Bully Breed dog

First let me state that I am an advocate of the spaying & neutering of all dogs that are not kept for the purpose of breeding.  We do require all customers to sign a spay & neuter agreement as part of our Purchase Agreement unless such dogs are purchased by approved breeders for breeding purposes.  We do not specify at what age they must be spay or neutered and leave this up to our customers and their vets to decide.

Now that said; there is much controversy as to the pros and cons of spaying & neutering and the best age to do so.  I am not a veterinarian nor have I personally done extensive studies on this matter.  I have done significant research on this subject and have read the studies done by others and my conclusion is; I would not have my female large breed dog spay any younger than 6 months and if possible would wait until 14 months after her first estrus cycle.  I also choose to wait until 18 - 24 months for my large breed male dogs.  I however as a breeder am in a different situation than most pet dog owners and am set up and prepared to handle the issues associated with intact dogs.  I recommend to my customers that they do their own research on this matter, discuss it with their vet and make their own decision.   

Fact:    Depending where you find your information; your chances of being bitten by a sexually unaltered dog are usually about 3:1 greater than being bitten by a sexually altered dog.  Some shelter/rescue organizations claim that 70 - 90 percent of dog bites are from sexually intact dogs.  I was able to find this number on many shelter/rescue type websites but was unable to find an actual study that proves it true.  The fact does still remain that sexually unaltered dogs are more likely to bite.  We have been breeding dogs for over 40 years.  We have found in our own dogs that this has been the case and that otherwise very mellow laid back male and female dogs can become far more aggressive when a dog in the pack is in estrus.  Another reason for this statistic is that the less responsible dog owners among us are more likely to put off sexually altering their dogs.  They also are more likely to have poorly socialized under-trained dogs and more likely to allow their dogs into a confrontational situation.

   Fact:      There are many opinions on this matter and more research is needed in this area of dog health.  For more information follow the link below for examples of some of the research that has been done in this area.
