I have heard, for boys, you should get them spayed by 3-4 months, so that the hormones that make them mark, hump, and be macho manly don't appear. But if you wait past 4 months, bad habits can start to form. For girls I heard before 6 months so they don't go into heat. My girl was 5 months and not even 2 lbs when I had her spayed and she did great. |
