My dog is throwing up, not eating, shaking, panting. When to see vet?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | unspayed | 35 lbs

For the past two days my dog has been throwing up, refusing to eat, shaking and constantly panting. It also appears like she may be constipated and some kind of liquid could be coming out of her rectum. She is 10 years old and, I'll admit: a bit overweight. She also has what the vet referred to as a mammory gland node. I could not get this removed as it cost way too much. It doesn't feel any different now than it did a year ago but I figured I'd include that just in case.

I would recommend taking Pups to the vet. These symptoms are very concerning, and probably not related to her mammary nodule. It could be dietary intolerance or indiscretion, food allergy, intestinal parasites, GI blockage, gastroenteritis, bacterial or viral infection, IBD, pancreatitis, among others. The straining and liquid is likely severe diarrhea - similar to humans, you can strain with diarrhea and have nothing come out. The vet will do a thorough exam and may recommend blood work or x-rays to determine what is going on.
