What Is The Brown Discharge Coming From My Dogs Vagina?

It is normal for dogs and cats to have a slight discharge at certain times, such as when they are in heat. Most of the time, however, a genital discharge is a sure sign of infection, and you will need to take care of it right away.
Females that have recently had a litter are also prone to uterine infections. What sometimes happens is that part of the placenta stays behind after delivery, providing a fertile breeding ground for bacteria. You should suspect that something is wrong if the new mother, who is generally overprotective, ignores her offspring or refuses to eat. This type of infection usually causes a foul-smelling vaginal discharge that starts out watery and a little red, and then gets thicker and turns dark brown and contains pus as the infection progresses.
It doesn't happen often, but an infection and discharge may occur after dogs are spayed if a little bit of the uterus was left behind. If your pet is listless, lacks an appetite, drinks a lot of water, and there is a discharge too, take her back to the vet immediately.

This discharge does not sound normal.  Once a dog gets pregnant it does not start discharging a brown discharge.  Right before delivery a mother can pass a mucous plug but this should not be a chronic or ongoing discharge.  It would be best to have this dog examined by a veterinarian.  They can look at this discharge to see if there is an infection present.  Pyometra or uterine infection is a serious and potentially life threatening disease. 
When did she mate?  Pregnancy in dogs lasts 63-66 days.  So if you know the date of breeding this should help you decide if your dog may be pregnant.  Pregnancy can be diagnosed via palpation at day 22-26, by ultrasound examine day 20-22 and most accurately at day 26.  The fetal skeletons calcify at day 45 and can be seen on x-rays.  Please talk to your veterinarian if you have further questions.

Brown discharge during labor in dogs is normal which means process of whelping has begun. Any vaginal discharge during pregnancy of dogs other than during labor is not normal. It can be miscarriage and is medical emergency. If your dog is in labor and having brown discharge then it is OK, otherwise, it is medical emergency.

It is only normal if your dog just had pups and even then it should not last over a month or she probably have and doggy std

My dog has bloody discharge

My St. Bernard is maybe around 61 days of pregnancy, She has been spotting dark brown blood for 2-3 days, she has been panting some. Is this normal and how long can she be in labor?

She is on her period, I think. Perhaps you should take her to the vet.

It is absolutely normal for your dog to have some form of discharge but in case of the brown discharge, this could indicate infection. I would suggest you get her to the vet without delay as this also can help you rule out if she is pregnant. Good luck.
