Hi Dr Peter,
Basil is a six month old border terrier. I think he weighs around 5 kilos. We walk him regularly in different parks, as far as I am aware he hasn't eaten anything dodgy but I don't really know. Again, as far as I know he doesn't have any pre existing medical conditions. Today and Tuesday when he was first sick he is more sleepy than usual. When he is well he is a very lively puppy.
He has had diarrhea, the first day he was sick. He did a normalish looking stool this morning after he was sick. He vomited today at around 9.30 so 3 hours ago. His gums are pink but they are quite pale.
