Hi guys, on my phone - so I apologise if any spelling mistakes occur. Autocorrect!

I have been reading the book of the bitch, and researching why Bella is in heat for so long. A quick summary;
She swells from day one.
She bleeds throughout. Though its only very light. Some days we have no blood, then it continues.
She usually bleeds lightly for about 21 days.
I have rang our vet and they said its nothing to worry about.

I have no come across pyometra, and really worried, but struggling to find out more. Has anyone had this? I'm worried Bella bleeding for so long through her season is linked to it?
I am a complete worrier, so probably panicking for no reason, but just wanted to check it with you all?

Let me know if you need anymore info from me xx

Hi Pyometra is heralded by a yucky discharge,

Pyometra is a result of hormonal and structural changes in the uterus lining. This can happen at any age, whether she has bred or not, and whether it is her 1st or 10th heat (although it becomes more common as the dog gets older). The main risk period for a female is for eight weeks after her peak standing heat (or estrous cycle) has ended.[1] Normally during this period, the cervix, which was open during her heat, begins to close, and the inner lining begins to adapt back to normal. However, cystic hyperplasia of the endometrium (inner lining of the uterus) – known as cystic endometrial hyperplasia (CEH) – may occur at this time for some animals, as an inappropriate response to progesterone.
Under these circumstances, bacteria (especially E. coli) that have migrated from the vagina into the uterus find the environment favorable to growth, especially since progesterone also causes mucus secretion, closes the cervix (preventing uterine drainage), and decreases uterine contractility.[2] The condition of the cervix is a major factor in the severity of the condition.
If the cervix is open, the infected material can leave the body, and this is far easier and safer to treat. This is known as open pyometra.
If the cervix is fully closed, there is no discharge from the vulva, and like in appendicitis, the uterus may rupture and pus escapes into the abdomen, causing peritonitis and possible rapid death. This is known as closed pyometra.

Hi Pyometra is heralded by a yucky discharge,one of mylate fathers greyhound had it, I was only a girl, but know that this greyhound had phantom pregnancies, so her cycle was interrupted,So please dont worry and if your vet has said the same,I would be thankful that your vet is honest,and doesnt want to just make money.Keep a diary and you will get to know her cycle crystalgirl

Pyometra usually occurs a few weeks following a season .
I think this is a good brief description.
