I very strongly believe in waiting until at least 18-24 months. It gives the dog plenty of time to physically mature. You can usually easily tell the difference between a dog that was neutered at around 6 months from a dog who wasn't neutered until he was at least 18 months just by looking at them. The ones who aren't neutered until later in life usually have much blockier heads and fill out more physically, while the ones who were neutered around 6 months usually have a much narrower head and tend to be lankier. I would wait. I firmly believe that 6 months is way too early.
Also, does your breeder have a contract on when to neuter?
Our vet said they would have dropped by now, one seems like it is on the way down. I didnt know since neither of his balls dropped would we be at risk of anything if we waited 18 monthsHave you seen your vet about his testicles not descending? By 6 months, they definitely should have already dropped. There is a condition called cryptorchidism, which is when the testicles do not descend. One of our dogs when I was a kid had this.
At Hank's last vet visit, the vet mentioned his had dropped (10 weeks old). I ask when is normal, he said usually by 8 weeks.Neither of his boys dropped and I have heard anywhere from 6 to 12 months.
