i'm asking on behalf of my boyfriend. i said yes take Gus to the vet asap and he said yeah, i already made an appointment.
i know when poop is black thats a bad sign so i'd imagine black vomit would be equally bad...? i have no idea what it could be though. he said his dog vomited a second time and there were little worms in it, like maggots.
i hope Gus will be ok...
