We've been on Formby beach today with Romeo and there there were loads of little jelly fish (i think?!). Romeo out of the blue just started eating them, we kept trying to get them off him but he must have eaten at least 5. Has anyone else's dog done this and is this something I should be worried about. He has been totally fine since eating them which was now several hours ago and he has eaten his tea with the usual gusto and shows no sign of any discomfort. Do I need to worry or is it the equivalent of eating sushi??
