My dog is throwing up bloody vomit and is in heat. What to do?

Updated On September 23rd, 2025

Pet's info: Dog | Maltese | Female | unspayed | 4 years and 9 months old | 4 lbs

What should I do? My precious girl has been throwing up a lot this morning (3 times) and it seems that she threw up something white and reddish and it looked pieces of meat or something, she hasn't eaten all day and is resting right now. She's also in her third day in heat right now.

This episode may be dietary related and completely incidental. As a first line approach, I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, lethargy or inappetence. 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.

    It could be possible, yes. I can give you a home remedy for Elphaba to see if that helps. Withhold food until the morning, 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 refuses to eat the bland diet, 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. I hope this helps!
