My dog has white discharge after heat. Should I be worried?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female

I am very worried about my dog! Today I found a white discharge and I saw online that it could be dangerous, I don't know what to say or to think but I don't want her to die. I'm really sad, though she seems fine I don't know if she really is. Can someone please help me, I am working on scheduling her an appointment to the vet. She's a very small dog and I've had her for about 4 years. She has been in heat but this is new to me I've never seen this before.

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.
