how do i know when my shih tzus in heat?

my shih tzu is 11months old and i do not konw how to tell if she is in heat or if she is going into heat.

The average heat cycle for a dog is approximately 3 weeks and since this an an average, some heats are shorter (as little as 7-10 days), others are longer (4 weeks or more).

Average times between heat periods is seven months but some dogs can cycle as early as every 4 months, some once a year.

Lengths of heat cycles and intervals between cycles are different for each dog but most dogs hit somewhere close to the averages.

The first part of heat you will notice bleeding from the vulva, swelling of the vulva, possible increase in urination and the most noticeable, male dogs hanging around the house. During this period (proestrus), females will not allow the males to breed with them although the males will be very persistent.

The second part or estrus is the time in which the female will allow the male to breed her and this can last anywhere from 4-21 days. A female, most of the time, will allow most any male to breed during this time. As the female starts to go out of heat or enter diestrus, she will be less willing to breed.

Again this stage can last 4-14 days but averages approximately 7 days. The next cycle usually begins about 7 months from the start of the last heat cycle, not the end of that cycle but again this varies from dog to dog. The interval stays the same even if she becomes pregnant.

If you do not intend to breed her, you really should consider spaying her. There are many health benefits associated with spaying such as decreased chance of mammary tumors and you will not have to worry about pyometra, metritis or unwanted litters (overpopulation is a big problem – just take a trip to a humane shelter).

If you elect to spay her, this can be done during heat but it may be best to wait until the heat cycle is over to decrease the chance of complications.

    why isnt she spayed? if you are planning on breeding her (the only reason to NOT spay her) it is not a good idea if you have to go online and ask this type of question. breeding a dog isnt somthing you do in free time. you have to know what you are doing. might as well get her spayed. its the responsible thing to do…

    Well, definately do NOT breed her during this heat.
    This is her first season and you could have some major problems.

    First thing you might notice is a change in behavior.
    She may be more playful and outgoing than usual.
    Also, a bloody discharge that will turn white in color is often noticed.

    Although, some dogs barely spot while others can literally almost soak your rug!

    You might also want to take a look at her vulva.
    Is it swollen and bigger than usual?
    If so… she prolly is going into heat.

    But… PLEEEEZE do NOT breed her during this heat.
    With her being a small breed and it being her first season… I wouldnt doubt that she may have problems.

    Especially consider getting her OFA cleared of all Shih Tzu heritary diseases BEFORE breeding her.

    Good Luck though!
    And give her a big kiss for me!

    Does all shihtzu bleed, i heard some comments that his pet shihtzu is difficult to notice because she does not bleed when the dog is in heat?

    well my Pup is 9 months and i still haven’t notice her in heat. but my Pitbull she bleeds all over my back yard and all the dogs come to my fence and start barking trying to get in maybe its more noticeable on big dogs?

    My shih-tzu just turned 6 months old I acually have an appt to get her spayed in 2 weeks, but I’m pretty dang sure she’s going into heat. Is it weird for her to start it so young? Everyone I’ve read about say’s theirs are 1+ yrs old.

    hi, my shih tzu is just 8 months old and started about a week ago…noticed by small blood spots. Not very much at all but I have wood flooring all over apart from the stairs so maybe if she was staining everything I would probably notice more. I dont intend to breed her as I think you need to know what you are doing and I don’t, so I will be getting her spayed after the heat period.
