hi hamilton, i have 3 pbp's. i don't have an answer to your question but i will post this at a couple of yahoo groups and see if i can get any ideas for you.

nina :)

i did some looking around at allexperts.com and found this answer to a question about a pbp losing its balance (i will put it in quotes)...

"Pigs have narrow ear canals that are easily blocked, and blocked ears can affect balance. Lack of balance can also be caused by neurological problems like stroke or salt poisoning. Antibiotics will not fix any of these problems.
Make sure her ears are clean but do NOT squirt liquid into the ears and do NOT allow the vet to flush them with water. Both cleaning techniques can cause the ear canal to plug with water, making things worse and causing deafness.
A blood test will help your vet determine if this problem is caused by an infection, and if so, which antibiotic is best."

i hope your oinker gets better and hopefully, antibiotics will help if it's a simple ear infection that is causing loss of balance.

fyi, if you feel so inclined, you should post some pics of your piggy in the gardenweb pets forum. i do occasionally and the other folks there love seeing them. :)

THS has a pets forum. I don't get the impression that this is a work animal or a food animal, perhaps you should ask there instead.

Here is a link that might be useful: Pets forum

I realize this is a very old post, but can you tell me what you found out? My pbp is 2 years old and started doing the exact same thing this weekend. When she stretches up to get a treat she stumbles sideways. Any information you can give about your experience would be greatly appreciated!!
