Why is my dog vomiting foamy fluid, not eating, and lethargic?

It sounds like your dog is sick. The drooling can be due to nausea, and the lethargy, vomiting, anorexia, and diarrhea could be due to a severe GI illness, eating something rotten, pancreatitis, or a foreign body. I would take your dog into a vet right away for an exam, he sounds quite ill with all these symptoms, and he needs to be medically treated ASAP.

It sounds as Romeo is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

Rockie is adorable and I'm sorry to hear that he isn't feeling well. After eating a heavy, greasy meal, he may have developed gastroenteritis (inflammation in his stomach and intestines) or pancreatitis. Aside from assuring that he is drinking water and offering a bit of a bland diet (boiled white meat chicken and rice) as you have done, there isn't anything more that can be done at home. Young puppies are more susceptible to the effects of dehydration than adult dogs and need to be treated a bit more urgently. At this point, Rockie needs to take a trip to the vet for an exam, diagnostic testing and supportive care (IV fluids and medications). I hope that he is feeling better soon!

Poor Dingo! It sounds like he is very ill at the moment. He could have a severe GI illness, could have eaten something rotten, could have parvovirus if he isn't vaccinated, could have a foreign body, or could have pancreatitis. His symptoms are severe enough from your description that I feel he needs an immediate vet visit. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck, I hope this helps!

Oh no, that's not good! It's quite serious when a dog can't even keep down water, and it can be caused by a severe GI illness, pancreatitis, a foreign body, or eating something rotten. This requires an immediate vet visit so the cause of the vomiting can be diagnosed and treated. Please take your dog into a vet now.

The white liquid is most likely frothy saliva. With this combination of symptoms, I would recommend that Rocky be examined by a vet. Constipation is possible, but other GI issues like an obstruction or pancreatitis can cause the same symptoms. The vet will do a thorough exam and may recommend abdominal x-rays or blood work to determine what could be going on.

Vomiting can be a sign of a number of different problems ranging from minor issues like eating a non-food item from the yard to more serious diseases. Sometimes after vomiting dogs can feel nauseous or weak, so I wouldn't be too concerned about Poochie not responding to his name unless he also seems disoriented or extremely lethargic. If the vomiting continues or he continues to act very abnormal you should see an emergency veterinarian. While it is probably okay to drink a little water I wouldn't encourage him to drink too much as this can sometimes trigger more vomiting.
