I have a question for all the experienced ones out there.Here is the story.I had Maggie spayed a few months ago so i would be safe before she started.The last couple of days Neo has been trying to hump her(her head toooo).So my question is when female get spayed do the still give off a smell of heat that drives the males crazy?If so does this happen every 6 months or so?Also do they tie to gether as if breeding.I thought that once you fix a dog they DONT have sex.Please any information would be appreciated.
