My dog is due to get spayed next week, she's about 6 years old and well behaved - only problem with her is outside off the lead. She'll meet other dogs, do the usual sniff around and then try to put her paws on them in a dominating way. This then often leads to fighting!
She's no longer allowed off the lead until we get her trained better, but I was wondering of any of you that have had dogs spayed, have you noticed much of a difference afterwards in your dogs behaviour?

Briano, if it was something to do with her not being spayed, it'll probably make very little difference now.

A natural behaviour very quickly becomes a learned behaviour if it is repeated enough so no, I don't expect it'd make much difference.

If the reason she does it is because she's uncomfortable, it may make her slightly better with other dogs not having hormones in the way (although unlikely at her age I think), but if it's over exuberant play it'll probably make no difference.
