Should i sterilize my dog?

If you are not gonna use her for breeding purposes, then yes I would deffinatly have her neutered, some vets suggest her first season should be had first due to maturing purposes where as others will neuter her around 5-6months old .. Neutering her will be better for her health aswell as she won't have the worry of been chased by entire males when she's in heat etc, she won't be at risk of the female cancers aswell as fake pregnancys etc.
