I have a 5 and half year old welsh section d had him for about a year and a half. About a month ago he had colic symptoms had the vet out and after buscopan vet said he had undigested matter so no food overnight and he was as right as rain. It has occurred again tonight vet didn’t come out but gave him Danilon and no food overnight. He had his first outing on spring grass today so maybe that was the reason for today but he was fine last year. No idea what caused it month before. Vet wants him to stay on shavings have wet hay and food and no sudden changes of routine. Any idea why this is happened all of a sudden anyone experienced anything similar.?
