Why Dog Vomit Mucus. Kennel cough and other upper respiratory problems may cause dogs to cough up foamy white liquid. If you notice any parovirus or kidney disease symptoms, go to the vet or pet er.

Dog vomit can appear clear, yellow, brown, or white and foamy. If your dog has been throwing up a lot of clear mucus this could also indicate water intoxication. This happens when your dog has ingested too much water.

What Does Green Mucus Mean In Dog Labor. Heavy uterine bleeding, abdominal pain, weakness, or other signs of maternal distress. If the mucus plug is green, bloody, or stinks, that's a red alert.

An unborn dog developing a mucus plug beneath the cervix makes the uterus and fetus less vulnerable. If the discharge appears and your dog has still not had puppies after a few hours, contact your vet for help. Puppies are stillborn or are alive but seem weak or not normal.
