Reasons to neuter your pet (castrate or spay)
Fighting or aggression
Unwelcome frisky attention
Reduction of the risk of prostate disease, pyometras and mammary gland disease
Your pets metabolism will change, so if they eat the same, then they will put on weight, so sometimes a slight change of diet is required.
and that's pretty much it. A very small proportion of bitches become more aggressive after speying, but this is very small, and may be linked to speying too soon after a season, and the dogs innate behaviour beforehand. It's so infrequent, we don't usually consider it.
Some owners want their pet neutered to try and quieten it down. While neutering can help to a degree, its often not the whole story, and in a lot of cases there is very little if any change.
