I'm so sorry to hear that Boomer is sick! It is very concerning that Boomer is throwing up everything including water. The vomit being coffee colored makes me concerned about a GI ulcer or serious GI bleed. This can occur secondary to toxin ingestion, kidney failure, or overdoses of some medications. I strongly suggest you take Boomer to an emergency veterinarian so he can be examined and supportive care can be started. He will likely need blood work to determine what the underlying cause.

Unfortunately without emergency care Boomer is at risk of becoming dehydrated and the illness worsening. You can try a bland meal of boiled chicken and rice however I don't think this will resolve the issue so I'd still encourage you to seek veterinary care for Boomer as soon as possible.

Thank you for using Petco Pet Education Center, formerly Petcoach and I hope Boomer can get the care he needs and is feeling better soon!
