Dog is almost 18 months she had her first season beginning of Nov and since then (even when not in season) she has been so intolerant of male dogs. I dog walk with a friends make dog coming up for a year and he's allowed to sniff and lick but the minute he puts a paw on her back she chews his head off (never hurts him but shows teeth etc) never puts him off because he keeps coming back. Same with another two males we know. The makes seem relentless to hump her given half the chance even though she's no longer in season. I thought they would give her a break if she wasn't in season.
First make dog is being castrated this week and my dog is being spayed beginning of next month so hopefully it will no longer be a problem.
