My next door neighbors claim to be responsible breeders, yet their female American Bulldog burst through my fenced in yard and tried to attack my kids last week with no provocation. My Akita, who's military trained and spayed, is all that kept the other dog at bay.
Military dogs are routinely spayed and neutered to keep health issues to a minimum and to keep their focus on the jobs they are required to perform. My Akita is focused on us instead of constantly going in and out of heat and wanting to wander and break out of our yard like that dog did. It took 2 animal control officers to subdue the enraged dog.
While you both may be responsible breeders, the majority of breeders I've come across don't seem to be. I've helped rescue multiple dogs from breeders that were actually puppy mills. I've had 2 blind pugs and a pug that had deformed legs. Nothing will convince me that keeping dogs and cats 'intact' is a good idea. There are plenty of shelter animals who need homes and are euthenized instead. My Sachiko was a lucky one who was a puppy rescue by an ex marine who worked with the k9 unit and I was blessed enough to be chosen to have her when her training was done.
