Daisy has just finished the third week of her season and is fine in herself. For the past couple of days the blood ....which is hardly anything now, just small marks when she sits on floor, is more of a browny red.
A friends daughter has just lost her bitch from eclampsia and I got my dog book out to read about it. Whilst reading had a look to see if I could find out about the colour of the blood and it seems it should become lighter, which I am sure is what happened last time

..my memory is so bad

Of course now I am becoming a bit paranoid and am googling and worried it might be Pyometra
Am I worrying unnecessarily or should I take her to the vet?
