Hi, newby but had problem similar the last couple of weeks with my 4 year old boar Sheepy. At first started with starvation after the loss of his friend, which I posted about and my success with getting him a wife who helped immensely.
But after a few days was losing weight again and wasn't drinking so once again worried and off for third trip to vet in 8 days. Another X-ray for something. Nothing.
Checked teeth yet again but even after my pointing out of very sore by bladder etc knocked him out to check teeth. I was desperate so thought could be a problem and the lack of food was causing the pain as was suggested by vet (lack of sleep with feeding through night and prodding to check if alive after the paranoia a death of a piggy brings!). All fine as the majority of my brain thought.
Had another x-ray. Looked normal. Other than caecum looked swollen. And bladder smaller small. Got home after he'd been in their care 24hours and there were blood spots on the blanket were snuggling on after the slightly forceful syringe feeding. Then blood in wee. Went there again. Later on discharge and blood.
Phoned the vets and was told there was nothing else they could do but carry on with the septrin, Zantac and metacam I'd requested or euthanise. A rabbit friendly vet in Rugby!
So on the phone to Cat and Rabbit Care clinic at 19.30 booking an appt for the morning! Cost me over £30 to get there, wasn't going to trust a vet that said they could do nothing! Even after spending hundreds!
Saw Kim, said my pig was very poorly and had most probably bladder sludge which the other vet should have dealt with when knocking my poorly pig out in the first place! By flushing out his bladder which had been obviously causing him pain.
He's now on Zithromax, still getting his appetite back but has gained although feel guilty pinning him down for syringe time! So although I've always tried to give him a good diet since adoption don't know if illness or diet can bring on these issues? Hoping the wonder drug works for Sheepy so maybe that could help?
Hoping he's still a happy pig. Have lots of types of hay to encourage Sheep to eat at the moment but fave is always grass! Hope he does well, know how sad they can be as going through it now!
