Need some opinions: I have a Maltipoo/yorkie mix who is just over a year old. He stays in the house the majority of the time and his outside time is spent on a leash or supervised. I've read that it's better to get it done while he is younger. I don't plan on breeding him but my aunt (who I got him from) said I might want to later on. Should I get him fixed or keep my options open? Is there anything else I should be considering?
