Length of heat

[cactustime]

My puppy is 2 weeks into her first heat. It's pretty full on! Wasn't quite expecting this. When will it end - internet advice is inconsistent so just looking for anyone who can be a bit clearer. She's a miniature labradoodle - been 'bleeding' for two solid weeks, very swollen down there but otherwise seems ok. When will it end?
Thank you

It varies for each dog my dogs heat lasted for 4 weeks, but it tends to be around 3 weeks.

Following as am expecting my pup to start some point soon, she is 8 months almost

Our dogs first heat lasted just over 3 weeks.

Our dogs heat lasted around 3 weeks but she has been suffering from a phantom pregnancy ever since, so something to watch out for. She was really good though so very little mess as she self cleaned a lot.
