My DanexBoxer girl is in heat again. She last came into heat roughly 4, maybe 5 months ago. Now she's in heat again, right now she's bleeding (normally, not excessively). I was wondering, is this really normal? She's a year and seven months old. Not too terribly active exercise wise at the moment, due to the horrible heat 24/7. Usually I work her over small jumps, practice send-away, retrieve, and heel commands, things like that. Nothing in particular, really. She is a VERY healthy dog, perfect weight, shiny coat, bright eyed, UTD on everything. Very energetic, just lacking minor muscle tone (when we train her hindquarters get HUGE and her back is nothing but muscle). I first noticed that her nipples seemed baggy, and that she was licking excessively. My first thought was, "OH DEAR GOD NO SHE'S PREGNANT" then I got a hold of myself and realized, nope, she's just in heat again I was also wondering: When do dogs become fertile? After the bleeding period or before? Hazel normally sleeps outside on calm nights (i.e, warm with no rain). The past three days though, she's been finding new and creative ways to escape. First she found a weak spot on the bottom of the door, squeezed out through it. Fixed it as soon as I found out. Next she found a weak spot between two posts, so she squeezed through them. Fixed it. THEN today I watched her, honest now, JUMP OVER THE TOP OF THE KENNEL. This is a 7-8ft high kennel and she was able to get over the top. I couldn't believe it. She hopped over the chainlink fence this morning when I went out to feed the chickens, I thought she chewed through the chainlink somehow! It's covered for shade except for one small area in the front, which is were she decided to escape. On the one side, I'm amazed at her athletic ability, on the other side, it really worries me. For one thing, she's far to young for that kind of bodily strain. And, thats a great way to get pregnant by a passing mutt.
