My dog is lethargic, hunched, coughing, vomiting white foam. What now?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 40 lbs

My dog is very lethargic, walks somewhat hunched over as though she is in great discomfort, and acts unusually apprenhensive around me. Her appetite has diminished and she has been coughing and vomiting a frothy, foamy white substance? What should I do?

Sounds like Mama is definitely in a pretty significant amount of pain, and probably experiencing some nausea as well. In order to determine the cause, a physical exam should be performed by a veterinarian. They will be able to tell you if further diagnostics are required to come up with a reason for Mama's current state. In the meantime just so you can be sure immediate attention isn't required, consider obtaining a temperature (normal is 99 - 102.5), checking the gums for pinkness / moisture, and checking the skin for normal elasticity. If Mama appears stables in these regards, there is no reason to think she needs to be rushed out tonight.

    Hello, and thanks for using Petco Pet Education Center, formerly Petcoach. Bruno really needs to be seen by a vet to determine what's wrong. Decreased energy, exercise intolerance, decreased appetite/thirst, vomiting, and coughing could indicate heart disease, kennel cough, pneumonia, cancer, etc.... a thorough exam and potentially chest x-rays and bloodwork would be needed to determine what's wrong and get Bruno on the right medication. Hope this helps!

    I hate to hear that Jasmine is so sick. She sounds like she is pretty uncomfortable. These can be signs of many things including some serious conditions such as an intestinal blockage, stomach torsion or pancreatitis. I would recommend to have her seen today. The rapid breathing is likely an indication of discomfort which is the most concerning. I hope she starts feeling better quickly!
