No, most mares are in heat for 5-7 days; longer than 14 days is a sign of trouble and should be examined by a veterinarian.
A mare may become more tempermental when she is in heat, and possibly more agressive. Another characteristic that a mare is in heat is what is called flagging or winking. A mare may lift her tail in front of a male horse to get his attention. The most sure sign that a mare is in heat is her acceptance of being near a stallion. If a mare is in heat around a stallion she may squat and urinate showing she is ready to breed.
In the cold months many mares show no signs of heat. But as the days grow longer and the temperature climbs mares have more obvious signs of heat. Every mare is different but they have a cycle about once every 4 to 6 weeks on average. Some mares have cycles closer together, some not as often. If the mare is bred and becomes pregnant she will have no more heat cycles until what is called 'foal heat' after her foal is born.
About 10 days after foaling, a mare will have a "foal heat". Although this is not a perfect time (because of decreased fertility and increased risk of early embryonic death) - this is the first time after foaling that a mare can be covered.
No. They can stay in heat for several weeks and then stop. Its important to remember that unless you breed them, or fix them they will go into heat more frequent for longer periods of time- this is biologys attempt at continueing the species.
some mares will mount other mares in season others will just also come into season. you may see extra urine output and also some squirting from the mare in season.
Normally, yes. My mare is always super fresh when she goes into it. However, I actually don't mind it much because it is a good excuse to not work on our barrel racing and switch to discipline. I feel like my mare going into heat is an opportunity for me to work on her respecting me and my control of her because she is more hyped up then normal.
The earliest a mare can be bred post foaling is during the post foaling heat which occurs about a week after the foal is born. It is generally acknowledged that the mare is less fertile during this heat cylce because the uterus is usually not completely clean and totally involuted (returned to it's normal size). However, if the mare doesn't ovulate until 10 or more days post foaling the chance of a pregnancy is much higher.
Darkening and thickening of the urine. Mares will also "blink" the vulva more during a heat cycle.
Not without veterinary intervention. It is dangerous and almost impossible to speed up the coming of a mare's heat. However if your mare is more than three and has not come onto heat, ask a vet to have a look at her. There are a lot of possible causes and most of them are easily treated.
Technically, a mare can be bred again on her "foal heat". Her first "heat" cycle usually a few weeks after giving birth. For big breeding farms they do rebreed the mare at this time. For most backyard horse people this time comes and goes without notice. They are too busy playing with their new foal and its nice for the mare to recover from birthing. There is usually plenty of time to decide if you want to breed your mare again.
no, go to a doctor, the normal is about 2-7 days!!
No, you should see your doctor you might be losing to much blood if you are bleeding for 2 weeks or more.
