Zoey and I love to visit our local doggy park. She normally does quite well and is getting great socialization out of our visits, and exercise.
The last two days however many of the male dogs have been paying very close attention to her and continually try to mount/chase her. These guys have all been fixed so i'm not concerned in that regard.
My question is can male dogs sense a female about to come into heat or is this strictly dominance behaviour and trying to establish order? Zoey is very close to being 5 months old. I had planned on spaying her before her first heat. From the behaviours today and yesterday of the males i'm worried her first heat is a lot closer than I thought. Shes showing no signs of already being in heat.
