If anyone has any ideas please tell me! I have a 5 year old male Nubian with no known medical issues. Yesterday he was stumbling around and did not keep up with the rest but was still able to get around. It has been really hot and humid for New Mexico and the signs he was showing were that of dehydration. I have forced about 1 pint of gateraide in him since last night, but this morning he will not stand up at all. He has tried but keeps falling. My vet thought he may have an infection, not sure why he thought that, but I did get him the penicillin the vet advised and gave him 1 cc sub q just now. Does anyone have any idea's? Henry was a rescue and my first at that! I have been learning from him but have no idea what to do at this point?
