He will be 18 months when/if I get him done. He has no problems other than being a bit of a blue smartie head. He doesn't hump, isn't aggressive, isn't sexual but he looks just like a young labrador puppy and with more and more dogs being stolen I am worried that if he is still in tact he might be stolen. We also do flyball and he is around 100's of dogs at the weekend and as he is a crossbreed I would hate for him to create pups being a crossbreed. Can you give me your pro's and con's for male castration. I've read on the web but would prefer personal reasons.
