My dog vomited red, but acts normal. Is it blood? What should I do?

Thank you for using Petco Pet Education Center, formerly Petcoach! I can definitely see that Koda's vomit is reddish in color and has some red flecks in it. It is possible that the vomit has blood in it, though I would not expect it to have flecks in it. It is possible that Koda ate something that was red/pink in color that made his vomit this color. However, even the possibility of blood in vomit is cause for concern as this can be caused by stomach ulcers, foreign bodies, or certain toxins. I recommend keeping a very close eye on Koda, and having her examined immediately if this happens again or your believe you are seeing something that looks like frank blood or dark coffee grounds in her vomit. She should also be seen immediately if you think there is a chance that she may have eaten something she shouldn't have or has gotten into human medications. Until she can be seen by a vet tomorrow, I recommend not giving her any food and only offering small amounts of water. There are emergency clinics in most cities that are open 24 hours. I hope this helps and that all is well with Koda!
