My dog ate McDonald's eggs. Why is he vomiting with bloody diarrhea?

Updated On September 23rd, 2025

Pet's info: Dog | Golden Retriever | Male | neutered | 8 months and 1 day old | 80 lbs

This morning when I wasn't looking, my dog ate my scrambled eggs from McDonalds. Later on, he was really gassy and farting a lot and when I had him in my car a few hours later he vomited clear liquid and chunks of the eggs. After he vomited he had diarrhea and just now he had blood in his diarrhea. He is an anxious dog in general and did get groomed today, which he doesnt really like. I thought I would include that. He is 100% up to date with his vaccinations and heart worm pills, etc.

Oh no, that's was naughty of Yeti to eat your food from McDonald's! It certainly sounds like the eggs has upset his stomach a lot, and that could cause the blood in his diarrhea. Eggs from McDonald's can be very fatty, and that can do a number on his GI system, and could potentially cause pancreatitis. I can give you a home remedy to try to see if that helps him with his upset stomach. 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 his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, has diarrhea on the bland diet, stops drinking water, starts vomiting water, or becomes very lethargic, Yeti will need to see a vet right away. Hopefully the bland diet helps with his symptoms, and he feels better soon!

    Feed Chop a bland diet of boiled chicken and cooked White rice for the day and see if you have improvements. If the vomiting persist, do not hesitate to take him to the vet for a physical exam. At the vet office they may want to perform an intestinal parasite exam, possibly testing him for parvovirus if is vaccines are not up to date and even possibly taking an x-ray to rule out a foreign body. I sure hope Chop only has a digestive indiscretion and hopefully the bland diet is what will help make him feel better. Thank you for using Petco Pet Education Center, formerly Petcoach

My 2.5 year old chiuaua / jack Russell mix has thrown up 4 times today with mucus/bloody diarrhea. Could him eating cooked steak and pork bones be causing this?
Yes, either or both may cause gastrointestinal upset or, more seriously, pancreatitis. If he is behaving normally otherwise, you can try withholding all food for 24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts. Begin with 1 tablespoon every hour and gradually increase the amount if there is no vomiting. Feed bland until the stool is normal then transition slowly to his regular diet. If symptoms do not resolve or if Emmitt develops lethargy, loss of appetite or abdominal pain, have him examined right away by your veterinarian. A simple blood test can be done in the clinic to screen for pancreatitis.

Hi there my dog has been having stomach issues today puking and liquid diarrhea in the house. He is 6. He’s usually ok and not sensitive and was fine yesterday . He clearly is under the weather and he ate something hot (got ahold of human food last n
Poor pup! The vomiting and diarrhea could be due to eating the human food but other things like bacterial over growth, parasites (worms and giardia) or even something more severe like an intestinal blockage could be to blame. The blood indicates that his intestines are severely inflamed. I recommend to have your pup examined by the veterinarian today if at all possible. He can receive medications that can make him feel better and resolve the inflammation much faster (and hopefully stop any progression of the condition). Sometimes times a bland diet can help and then a slow, gradual introduction to the normal food can be done. A bland diet can consist of 25% boiled white meat chicken and 75% boiled white rice. This should all be plain. Make sure your pup is drinking water. Break up the meals into smaller amounts than normal and fed more frequently. I hope your pup starts feeling better quickly! Please feel free to post any additional questions.

My dog vomited and has diarrhea. She ate some eggs out of the trash this morning. She is a 4 year old female, fixed, and up to date on all vaccines
if the dog is still active I would recommend to monitor her (watch for activity level, appetite, water intake, vomiting and diarrhea) and keep her without food for about 12 hours, then introduce bland diet such as boiled chicken breast and rice. BUT if the vomiting continues despite all of this, or your dog seems to be becoming more depressed or listless, or the dog not eating then call your veterinarian or a local emergency hospital.

I have an 8 year old mastiff who up until this morning was seemingly healthy. He refused to eat his food this morning and had two loose stools as soon as he was let out to go to the bathroom. He has vomited once. Later today he had two liquid stools
I can give you a home remedy for Diesel 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 his normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Best of luck.

I think my dog already have diarrhea. But he only eats eggs. What to do?
Diarrhea in dogs can be caused by GI illness, intestinal parasites, a foreign body, diet, or eating something rotten. Eggs are not a complete and balanced diet for a dog, and I would recommend feeding him a dry dog food instead. Make sure he is up to date on his deworming treatment, and if he's not up to date on his deworming treatments, you will need to get one from the vet. You can try a home remedy to treat the diarrhea. 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 a diet of dry dog food. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

Dog ate egg shells and has diarrhea. How concerned should I be?
Likely the eggshells are the cause of Luke's diarrhea. I wouldn't be too worried just yet, and 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 and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. Should the diarrhea continue on the bland diet, Luke starts vomiting, he stops drinking water, starts vomiting water, or becomes very lethargic, then I would be worried and have him seen by a vet.

my 8 yr old papillion male has bloody discharge diarriha that started yesterday. No vomiting and is in good health otherwise except not eating food but will eat treats. What should I do
If he is acting normal then you can withhold food for 12 hours and then offer him a small amount of a bland diet, like boiled chicken and white rice, and see how he does with that. You could also add a probiotic to his food. If the diarrhea continues, he starts vomiting, and/or becomes lethargic then he needs to be examined by a vet for treatment. He could have an infection, parasite, colitis, HGE, etc. and your vet can run lab-work to help diagnose and treat. Hope he feels better soon!

My dog weighs 20 lbs. He ate about 4 sour cream and onion chips. He now has diarrhea that looks kind of bloody, but no other symptoms. What is wrong? What do I do?
Poor Toby! It could be the chips have upset his stomach leading to the diarrhea that looks bloody. He hasn't eaten a large amount, so he likely should be fine. It's important to consider that this potentially bloody diarrhea could be due to another cause besides the chips, such as a GI illness or hemorrhagic gastroenteritis. 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 his normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Best of luck, I hope this helps!

my dog is vomitting blood and diarhea of blood? but yesterday hi vomit food with some plastic. what can i do for my dog?
I would have phivo evaluated by a veterinarian. Vomiting and diarrhea with blood can be caused by viruses such as parvovirus (if he isn't vaccinated fully) or can be caused by irritation in the stomach and bowel from eating things he shouldn't or by certain foods that don't agree with him. A veterinarian will be able to make sure phivo is hydrated, give him medication for vomiting and diarrhea, and do tests such as fecal exam or x-rays to sort out what is going on. If you absolutely cannot get him in right away, I would fast him for 12 hours then feed a bland diet exclusively (boiled skinless chicken breast and white rice). I hope he is feeling better very soon !

Poor Buddy! Diarrhea can be caused by a variety of conditions, including parasites, viruses, "garbage gut" from eating different foods or treats, among many others. Buddy may be having a bit of blood in his stool from irritation to the colon or parasites. Since you can't take him to the vet today and he is otherwise eating and drinking normally, try withholding food for the next 12-24 hours. After that time, offer boiled white meat chicken and white rice (1 cup of the 50:50 mixture for every 10 pounds of body weight, divided into 2-4 smaller meals) for the next few days. After several days on this bland diet, gradually mix in his normal dog food over another 5-7 days. However, if his diarrhea continues or worsens, if he becomes lethargic, stops eating and drinking, or has more blood in his stool, Buddy will need to go to his vet for further evaluation. I hope this helps and that he feels better soon!
