He's been sick twice this morning - first time foam and phlegm, second time, bile. One horrid poo - runny and lots of mucus. Wouldn't eat breakfast, very listless, occasionally shivery. I have a vet appointment for 2.45pm but am worried in the meantime - any thoughts on what this could be? He is very robust and never ill. He just came back from kennels yesterday and for various reasons had not had the kennel cough immunisation, but the symptoms don't seem to add up to that.
Thanks in advance.
