I think it is polio but I haven't seen a case personally. He is down, cant move his back legs (can some on the front), does not seem to be in pain, has a soft belly, no sign of diarrhea and still seems to have an appetite. Thanks to what I had read on here previously (thanks everyone!!) I suspected polio so I gave him Vitamin B complex (5 cc at 12.5mg/ml) twice yesterday (weighs about 100 lbs) and 1 cc of penicillin (300,000 units/mL). I also gave him a tetanus anti toxin just in case. He is still down this morning (gave more of the same). His temp is 103.0. Now his eyes are fluttering. I am dosing according to the bottles. He will eat sweet feed and I am using a syringe to give him gatorade. Am I giving him enough of each of the medicines? Does the lack of temperature rule out listeriosis and should I continue the penicillin? Also how quickly should he respond to the Vitamin B if thats the cause? Are there any other causes that I might be overlooking? Unfortunately I have to go to sleep (I work night shift) so I wont be able to answer questions right away. I hope I have said everything you need. Any help would be appreciated.
