How Much Is Too Much Blood for My Aussie's Second Heat?

Hi fellow Aussie parents! I am a newbie here. lol This is my very first time on this site and I got to say, it's quite an information station!

I have a one-year-old female Aussie named Isabella, or Izzie for short, and this is her second time going into heat. I definitely am noticing a bit more blood this time around, but she's in good spirits and acting like her normal self which has kept me from worrying too much about it.

I am just wondering how much is normal or at what point is maybe considered too much blood?

I appreciate anyone who can shed some insight for me! Thank you!
