I think when and whether to spay/neuter is a decision that needs to be made by every family based on their own needs and the needs of their own pet. Certainly the general trend has been toward later spay/neuter, typically after the dog is a year old if possible and i. The case of a female, after at least the first heat as well. That’s a HUGE change from when I got Kodi, when you were made to feel like an irresponsible pet owner if you let your dog go a day over 6 months without being spayed or neutered!
There is no hurry. If you want to research it more, feel free to do so. I found the booklet put out by the Puppy Culture folks (on their website) to be extremely helpful to me, and made me feel much better about my decision to delay Panda’s spay. (She is now 4 and unspayed, for a number of reasons, and like you, I know for sure that there is NO possibility of her becoming pregnant “by mistake”)
I made different decisions for my other two, and am just as comfortable with the decision I made for Pixel... she got spayed after her first heat and a false pregnancy... none of us were EVER going though THAT again! LOL! With hind sight, I wish that I’d waited until Kodi was a little older before he was neutered. I would not neuter a puppy at 6 months again unless there was a medical need for it to be done then. HOWEVER, I am quite sure that he WOULD have been neutered at some point. He is a performance dog. And while there are SOME intact performance dogs, there aren’t a lot. It takes a really special boy to be able to keep his brain engaged with the testosterone still raging.
But if I had it to do over, I probably would have waited until he was about a year old before having him neutered.
At the same time, I recently talked to someone who is getting a puppy. She works full time, and the person who will be caring for the puppy in the middle of the day cannot deal with a dog in heat. So she MUST have her puppy spayed before she comes into heat the first time. While I think, in the best of all worlds, it’s better to allow a puppy the benefit of adult hormones, in a case like this, you do what you need to do. Female dogs have been spayed at that age and lived long, healthy lives for years. I am sure this puppy wiil too. This person is going to be a WONDERFUL owner for this little dog! We all do the best we can for our dogs, but there are many different ways of doing that. That’s OK!
