My dog has vomitted 3 times in the last 8 hours. Each time it has been yellow liquidy stuff. It started about 24 hours after eating his regular meal. I didn't want to feed him another regular meal so I gave him some bread and then about an hour after that gave him some Cheerios. His most recent vomitting was about 2 hours after that. He is a lab/shep/sharpei/? mix, weighs 79ls and is 4 years old. He is acting fine other than the vomitting. Any suggestions? Thanks.
