Plus neutering increases the risk of all types of cancer aside from testicular (which has a low rate anyway) but especially blood and bone cancers, is linked to chronic UTIs and kidney failure, obesity, behavior and growth disorders, brittle bones, and obesity, It completely alters their personality (no more 'zip'. You don't get the same dog back that went in) and they lose their muscle tone.
Many people report dull coats but that's anecdotal and I can't show causality. Everything else comes from University (mostly rutger's)animal science department studies and studies done by pet food manufacturers and the american animal hospital association. Make the other owners accountable.
Report them. If they're on your property, shoot them. Your dog shouldn't have to be hurt because THEIR dogs are a threat.
Neutering him will not stop other dogs from approaching him. And dogs aren't pack animals, nor do they have alphas. Maybe you should do something about it, by properly containing your dog so the other dogs cannot approach him.
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.
