My dog has thrown up several times over the last few days, it's worse after eating he throw up undigested food and a lot of it pretty quickly after he eats. It started Friday night he did have a bit of my son's frozen meal pasta and butter with peas then some wet food threw that up. Threw up bile Saturday, had bread awhile later threw up a lot. Hours later had Rice and wet food threw that up, then food was withheld until tonight a little bit Rice and scoop of wet food and he threw that all up.

Given the length of time now and frequency of the vomiting I would recommend making an appointment with your veterinarian to Magellan examined. They will be able to take and full medical history and perform a full physical examination to try and determine the cause of the vomiting. They may also suggest X-rays of his abdomen to rule or any obstructions and possibly blood tests to check for any concurrent systemic issues. Your veterinarian will then be able to decide and prescribe a course of treatment which may include an antiemetic to stop any nausea, protectants for the gastrointestinal tract etc.

    Thank you for contacting Pet Coach with your question about Chunk. I'm sorry he's throwing up recently. I'm wondering if he's eating too fast leading him to vomit more often. I'd buy a slow feeder bowl online or at a pet store to see if that helps. In addition, I recommend a visit with the vet for a health check to be safe. Vomiting isn't normal, and that should always be examined by a vet. Best of luck, I hope this helps!

    Poor Ada! Yes, I would be concerned in that it's not normal for a dog to vomit and vomiting undigested food can be a sign of pancreatitis or a foreign body. If she is keeping water down and isn't lethargic, I can give you a home remedy to try to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. Good luck, I hope this helps!

    You haven't given him anything to eat so far and he's sleeping, so I would withhold food until Bruno wakes up, then feed him the bland diet. The vomiting could be due to pancreatitis, eating something rotten, a sudden change in diet, a foreign body, or a severe GI illness.
