Hi.. I have a 9 year old newf..he's been sick and had diarrhoea on and off for 2 weeks..starved him for 24 hrs and been feeding him rice or pasta.. Took him to vets last week and he said it's probably acid in his stomach checked him out no temperature gave me some tablets 3 times a day.. He stopped being sick for 2 days but odd bit of diarrhoea all week..then started being sick again about 3 hours after being fed a few days ago..going to take him back to vets tomorrow.. Just hope it's nothing serious..
