Is it normal for male dogs to become more aggressive after being nurtured towards males intact?

He is just becoming more mature. Some dogs change as they get older. And I am very surprised they let not neutered dogs at a dog park...omg!

Around here that would never be allowed, it is just asking for a fight. He is about at the age where his true personality is coming through. They don't mentally start to mature until they are 9-18months of age.

I would not take him to the dog park anymore, and work with obedience on leash, maybe even sign up for some classes! So no, I don't think it has anything to do with the neuter, just his age. Also, one week is pretty soon for such exercise after surgery, maybe he was still in some pain.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
