Thank you for your replies. We only feed Riley things like green beans, peas and maybe the occassional pinch of shredded cheese as a treat...but other than that he just eats his kibble...he doesn't like wet food. He has been eating this kibble for about 2 months..so its not a change in his diet. He hasn't thrown up today so we will just keep a very close eye on him. Thanks again! I will try the water thing to soften the kibble.
