poodle mix pregnancy

Question
my poodle is about 3 years old and she got "tied" three days one time each day on the 8th 9th and 10th of december. its been about 3 weeks and it seem she doesnt show any signs of pregnancy. today she came back in the house with light brown mucus coming from the vagina. does that mean she lost her babies or she fine?

Answer
Hi Lucy

Where was she in her season when you bred her, in terms of days?  

Light brown could be just the old blood, and you would have nothing to worry about.  Just keep an eye out and make sure her temp doesn't spike or she starts vomiting.

Good luck.
