O.k., the dog has been walked and I am researching the ‘serosanguineous discharge’.
I suspect it may be due to the ‘diapedesis of erythrocytes from uterine capillaries’, but I am not certain what diapedesis is.
Ah, it is the passage of blood cells through capillary walls into the tissues [then isn’t ‘the diapedesis of erythrocytes’ tautological? hmm]
On, BTW, the little sweetie is in proestrus, the first stage of the cycle, not estrus.
I’m not surprised a lot of things drugs have been developed for horses; very expensive horses can turn shy about breeding, can’t they?
Where was I?
vaginal walls to take-on a distinctive shape, a process known as cornification
the increase in estrogen causes an increased turnover rate of vaginal epithelial cells
Serum concentrations of estrogen rise during proestrus, leading to capillary breakage and leakage of red blood cells through uterine epithelium
This is getting to be way more than anyone want to know, right?
So, her vaginal and uterine walls are filing up with blood, that is leaking out of the tissue AND the type of cells lining them are changing; I suspect that means that they are being replaced with new ones (as opposed to the existing cells changing).
So, although no one is saying this outright, it seems to me that the serosanguineous discharge is a sloughing off of the uterine and vaginal lining.
What a surprise.
But the lethargy seems to be unusual; I only found references to increased activity.
And I trust you all to drug your pets appropriately; I just get unsympathetic at times because I have been blessed with perfect pets. (I never really like that couch anyhow.)
