I waited until Gracie was a year old because she was so small but I think it is best to do it before a female's first heat. For a male I would try to do it way before he becomes sexually mature to try to prevent a marking trend.
Several years ago a had a beautiful little Maltese female. She went into heat as soon as she turned 6 months. She developed Pyometra (a form of dog uterine infection) and nearly died. Thankfully they were able to save her but I usually advise people to get their female dogs spayed at 5 months. |
