pregnant pug

Question
I have a female and male pug, which I bred approximately 36 days ago, I am fairly sure that she is pregnant, she has become more agressive at feeding time, has gotten bigger in the belly, and her nipples are starting to swell.  My question is that today I just started to notice that occasionally she has a little discharge dripping from her vagina.(like if she were to pee and she would have a drop left that hadn't dropped off)It is not a considerable amount,  I just wanted to know if this is normal, maybe due to the pups sitting on her bladder, or if there is any need for concern.

Answer
While some bitches might have a bit of discharge early in the pregnancy and at the very end, they usually have a plug of mucus during most of the pregnancy as protection for the developing puppies.

Any discharge otherwise could be a sign of vaginitis or even pyometra (uterine infection), so it wouldn't hurt to have a vet take a look to make sure that everything is progressing normally. Keep an eye on her and watch for signs of lethargy, loss of appetite, increased thirst,
increased urination, and any other sign of illness.
