My Pug is pregnant

Question
This is my pug's 2nd liter and it is 62 days since they last locked.  My only concern is that she has been producing milk for the last four days, when or how will i know when she is ready to give birth?

Answer
She should loose her mucus plug about 24 hours before labor. She'll start to pant a lot. She won't be able to get comfortable. She'll start to dig, and maybe even try to hide. Make sure that you stay right with her when she goes outside. A dog that's in the first part of labor will also usually go off of her feed. Watch for these signs, and good luck!
