I have an 8 month old sweetheart that eats only eukanuba dry puppy food and the occasional treat/nutri-cal. I gave him a mini carrot yesterday and today I found out (when I arrived from work) that he vomitted the carrot in the morning, then a few hours later vomitted his eukanuba treat then a few hours after that vomited only water he recently drank. I gave him some nutrical and bought him wet food. He had a small amount of wet food. Should I be worried? go to vetenarian?
