Hi A, When my sheep have had bloat, it has been when they have gone onto new grass - after being on hay. Sometimes their legs and feet are sore as well as their feet seem to swell a little. But it does sound a bit like bloat. Id expect fast hard breathing as well, that is the main problem i think, that it puts pressure on the lungs and heart. And could he have got into any food like sheep nuts or grain? Cos that can do the same as very lush grass. Hay should help him if he has bloat. Hope the vet gets him sorted. Last time mine had bad bloat, i gave him antibiotics at the vets suggestion.
