When to neuter my puppy under our specific circumstances?
I have done a lot of research on when to neuter, and we were planning on waiting for 14-24 months. However, our puppy (now 8 months) is having some behavior issues coming up. Also, he has a retained testicle, so we were already looking to the lower end of the spectrum so that he may have a better recovery being younger.
We live in a city and don't have a fenced yard. We walk him multiple times a day but usually take him to the dog park once or twice to burn energy by wrestling or swimming. However, he's getting to the point where he's becoming fairly unmanageable. We've been keeping up with his training, but he fixates on female dogs and just spends the entire time trying to grab their scruff and mount them. We give him "time-outs" and re-direct, only to have him go back immediately. It's hard because we often leave the parks and don't get much play time in. There are other parks near our house, but his recall isn't as spot on as I'd like it to be near those busy roads with no fence, and since he's started rebelling more...
We're thinking about neutering closer to 12 months now, but I'd like to hear your thoughts! Is this behavior worth potentially risking developmental issues? His dad has perfect hips and his mom's are very good, just not perfect.
Thank you so much!
