Poor Capi! Sometimes rats are easier to catch for dogs due to rat poison, which can be very dangerous to dogs. Capi can be throwing up due to an intestinal obstruction from the actual rat carcass or have internal bleeding as some rat poisons contain anticoagulant toxins. I recommend having him seen by a vet right away, as he may need supportive care or vitamin K supplements (to replace the ability of platelets to clot). I hope this helps and am happy to answer any other questions you may have!
