Hello, just thought I'd get your opinions on what might be the issue with my boy Lucius. He has been vomiting since 8pm and hasnt stopped, our vet told us when he gets like this as he has a sensitive tummy we need to give him water little and often. after he was sick the first time he drank a small amount of water then was sick again, bringing up his water and a lot of mucus. An hour later we tried again, and a minute later he was sick again twice. He's brought up all his dinner which hadnt been digested at all from 5pm and brought up all the water he has been given. He hasnt been sick in a while and I thought that finally his tummy was settling but it seems not to be the case. He is on a strict wheat free, gluten free and beef free diet as he has many allergies. He has a history of gastritis and gastroenteritis ( i think that was the name i'm not sure though). Any thoughts? By the way if his condition does not improve he will be seeing his vet - we are hesitant to take him to an emergency vet as they dont know his medical history as well as our vet who is brilliant with him but if we need to we will. Poor little man feeling sorry for himself.
