Dog discharge after mating: Is she pregnant, in heat, or infected?

When you say you saw a white discharge you do not indicate where you saw the discharge coming from. Since you discussed heat later in the question I assume you mean you saw discharge from the vulva. An occurrence small amount of whitish discharge can be a normal finding. However, if you are noticing a yellow or blood tinged discharge, if she is drinking more than usual, if she isn’t eating well or otherwise acting “sick” then I would be concerned. Pyometra is an infection of the uterus and can be fatal. So if you are concerned that you are seeing abnormal vaginal discharge then she should be seen by a veterinarian as soon as possible. If this is the problem they will recommend to have her spayed immediately . Best of luck and I hope she is back to normal soon. Thank you for using Pet Coach.

Some discharge is normal but it is generally clearish or slightly opaque. Vaginal discharge can indicate an infection in the uterus. I recommend to have her examined today in case this discharge is related to a uterine infection. Uterine infections can lead to a life threatening septicemia so it's best to play it safe. Best of luck.

It could be a false pregnancy, true pregnancy, or a pyometra (though fluid from the nipples is less likely with this issue). The only way to know for sure is to have her examined by a vet. As long as her appetite and behavior are normal, I don't think you need to rush her in.

I am concerned that your dog may have a uterine infection which can be life threatening. White discharge after being in heat is not normal and can point to this. Since she is lethargic and not feeling very well I would take her back to the vet for a recheck.

It sounds like Margo may have an infection in the uterus or lower genital tract. This is most common following a recent heat cycle. I would advise that she be examined by her veterinarian to confirm this. If she does have a uterine infection, your vet can advise you about the best treatment which may include oral antibiotics or having her spayed depending on the severity.

This is likely the dissolution of the mucus plug. She will give birth within the next week and should start lactating soon. If the discharge looks like pus or has a bad smell. you need to take her to your veterinarian right away for an exam. Your vet can also take an x-ray and tell you how many puppies to expect so you know when she is done giving birth.

A moderate amount of clear, sticky vaginal discharge is normal for a pregnant dog, especially close to delivery of the puppies. The increased hormone levels cause an increase in the lubrication produced by the vagina. As long as there is no evidence of dark green color in the discharge, a milky or creamy appearance or foul odor no treatment is needed. It does not mean that she will give birth earlier.
