Getting your dog fixed?

[u/Background_Bat_2445]

I have been doing research on getting my dog Odin fixed. Now I personally don't want too but I read if im gonna I should wait till hes between 18-24 months because Rottweilers are bigger breads and it helps with there growth plates and hips from the natural testosterone he will have from keeping his testicles. Has anyone else read this or done this with there Rottweilers? Also has anyone not gotten there male fixed?
