How long do seasons last?!

[Sazzle]

Hi everyone hope your all well :- )

Just a quick question I've recently just got a 18month staffie and she's in season how long do they bleed for I'm now on day 18 and she's still losing a fair bit. My last two dogs were boys and my last bitch died on operating table at 2 so I'm not sure thankyou x

I can only go from what I have been told and that is that they can last up to a month.
