So my boar Pooh had diarrhoea (cow looking poos) for about 1-2 days. I stopped giving him veggies and made sure he was still eating and drinking. He got very poorly and just sat in the corner one evening, but he was still eating hay. I brought him to the vets that have been very good for when he was neutered, this time I'm not sure I can trust them completely and I'm hoping someone here can help me figure out what to do. The vet (one I have not seen before) started out with telling me Pooh was a very large boar at 1,1kg and he is more normal now weighing 800g?! I was quite confused by this as I see nothing normal in him losing 200-300g of weight over a couple of days! He then told me the weight was probably just him losing all the food he had in his bowels and since his poos are now looking firm again he should be fine. I am however still worried in case something is actually wrong with him or it will happen again, as all the vets did was feel him a little and look in his mouth. I asked them if they had any fibreplex in case it would happen again so I am prepared, and he said to also give him human c-vitamin mixed with water in a syringe. My question is really if I just leave it at that or should I maybe have him checked out by someone who's a bit more knowledgeable?
