Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Chase! Stress, vaccines, deworming, oral flea/tick and heart worm pills can cause inflammation of the colon and blood in the stool. If he is eating, drinking, not vomiting and not having loose stool I would watch him and see what the next stool looks like. It could be a one time thing. If one of the other things develops I would call your Vet to discuss and see if they will prescribe some medications. It wouldn't hurt to start a bland diet of boiled chicken or hamburger with rice for a few days. Good luck!
