What problem are you trying to solve?
If an overpopulation of dogs is perceived, why are you neutering males?
If you are neutering males, which males do you neuter first?
The big alpha ones who run the show and are intent to breed females in heat? Or the ‘satellite’ males, the ones who run around at the periphery and not really taking part of the action?
If you neuter the alpha ones, the satellite dogs will become the alpha ones. If you neuter the satellite dogs, the alpha ones still run the show.
Most of all, why neuter 5 year old indoor yorkie or chihuahua males?
What problem are you trying to solve when indiscriminately neutering males, or neutering small indoor males?
