Today doggy vomited with blood. Why? Is that because the hot weather in lebanon? Pet's info: Dog | German Shepherd | Male | 6 months and 26 days old

Hi, and thanks for your question. These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). Intoxications and coagulation problems cannot be ruled out. A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. If this answer was helpful please let us know, this will be used to improve our service!

I recommend to have Dubi examined by the veterinarian today. Vomiting blood is concerning for many different conditions including parasites in the stomach, a stomach ulcer, ingesting poison, hemorrhagic gastroenteritis, cancer or a foreign object trapped in the stomach. It could also be due to severe vomiting. Vomiting blood always warrants a visit to the veterinarian. Be sure to bring in a stool sample as well for testing in case the veterinarian thinks this is necessary. I hope this helps and please feel free to post any additional questions.

My dog threw up blood. What causes it and when should I see a vet?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Blood in the vomit indicates most commonly stomach lining irritation or ulceration. The only way heat could cause this is if Doggy is experiencing heat stroke (high body temperature, collapse, etc). When a dog is having heat stroke it is obvious and life threatening. Just general hot weather shouldn't cause vomiting let alone with blood. Causes of vomiting are: viral (especially parvo) or bacterial infections, intestinal parasites, he ate something inappropriate, pancreatitis, a blockage from eating a foreign object that is stuck, toxin ingestion, clotting or platelet problem or from something local to Lebanon. If he continues to vomit with blood that is an emergency and he should be seen by a Vet. If he is lethargic and won't eat currently he should see a Vet. Otherwise I would start a bland diet of boiled chicken breast with rice. Feed 1 cup per 20 lbs per day for 3-5 days to rest his stomach. i wish you the best!
