Why is my dog vomiting clear goo with blood? Is it his collar?
Updated on September 23, 2025
Pet's info: Dog | Australian Cattle Dog | Male | unneutered | 1 year and 5 months old | 40 lbs
Hey there, This morning, after our walk (run with a skateboard, to be precise), Dino puked up a medium amount of transparent goo with a couple of tiny droplets of blood in it. He has been treated for heartworm (fast kill method) more than a month ago and we have the green light for running. He hasn't eaten anything he shouldn't, as far as I am aware. Could I have done some damage with his neck collar? He was pulling quite vigorously this morning. Otherwise he is as energetic as ever.

After 2 days, you can put him back gradually on his normal food.
If he continues vomiting or is not eating, take him to the vet to get treatment.

Vomiting blood can be serious. If may be from something he ate, a stomach ulcer or an infection. I would withhold food and water for tonight since he is vomiting to let his stomach rest. You can feed chicken and rice tomorrow and if he does not eat, continues to vomit ir starts with diarrhea then he needs to be seen by your vet

At his age, sudden violent vomiting could be a sign of something serious, but maybe it's just something bad he ingested. withhold food for 12 hours then offer him boiled boneless chicken and rice every 6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food.
If he continues vomiting or is not eating, take him to the vet to get treatment.1Pet Parents found this answer helpful

If he's keeping the chicken and rice down it may be that he has some digestive upset going from the food change. It's possible there is an ingredient that doesn't agree with him with the new food, or that you are transitioning too quickly. If he's able to keep down the chicken and rice and is otherwise acting normal (no longer vomiting, etc), you can try with the old food once more for a few days, and then gradually increase (10-20% new food increments) over a period of 7-14 days to see if that prevents it from recurring.
However, if the vomiting continues, he doesn't keep down the chicken or rice, you see blood in his vomit or stool, he's painful or seems in distress, then it would be best to seek veterinary care ASAP to rule out any more serious issues causing it.1Pet Parents found this answer helpful
