I agree that the less invasive the better if there is a choice. But the term invasive needs to be used not limited to surgery but including substances that could be dangerous invading the body. Overdoses of zinc don't sound like a good idea to me.
Most of the dogs that have trouble recovering from neuter surgeries (done well) had to have a more invasive abdominal surgery to remove undescended testicles. These have to be removed in any case so getting an injection would not solve the problem here.
You can talk to God all you want and that's great, but the changes happen when you start listening to him.
BE THE CHANGE YOU WANT TO SEE IN OTHERS.
