My dog keeps throwing up foam. When should I take him to the vet?

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.

It could be, the pink tinge might be blood, indicating that he has swallowed something that injured his throat or stomach or he has vomited so much his esophagus is irritated enough to bleed. Either way, I strongly recommend getting him in to see a vet right away, especially if the vomiting has been going on for some time.

If Bogummy is vomiting that many times a day I would be concerned that he may have gastritis, pancreatitis, or some sort of liver issue (because of the head pressing ). I would recommend taking him back to his veterinarian and pursuing other treatments such as antacids or bloodwork.

If Jessi has been vomiting for the past 6 hours uncontrollably it would be best to seek veterinary care immediately. It is possible there is an underlying illness, foreign body or other issue that requires immediate care especially if she's continuing to hack and vomit for several hours.

Loki could have a severe GI illness, may have eaten something rotten, could have a foreign body, or could have pancreatitis. Given that he has been vomiting all day, the time for home remedies has passed and he needs to see a vet now. Please take him into an ER vet right away.

Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting can be observed with conditions such as gastroenteritis, pancreatitis, dietary indiscretion, gastrointestinal foreign body ingestion and obstruction, among other possibilities. For this reason, I highly recommend that you have Diesel evaluated by a veterinarian for further assessment and treatment as soon as possible as I am afraid he is likely becoming dehydrated. They would be able to check for these possibilities and also check his hydration status and give him medications to make him feel better. Good luck!

Poor Handsome! The shivering could be from pain or fever. He does sound like he is quite ill. If he is continually throwing up, I'd be concerned that he has a severe GI illness, pancreatitis, or a foreign body. I'm not sure of his vaccination status, but if he isn't vaccinated, parvovirus could be causing this as well. I recommend taking him into your vet now because he sounds so ill. Your vet can give him a shot to help him stop vomiting, and can diagnose what is causing his symptoms. Your vet can also start treatment to help him feel better. I understand being scared and sad, it's awful to see your pet sick. Taking him to your vet will help you be less scared and sad, as you will be getting help for him.
