That was really odd. Day before yesterday,I saw a cow walking with her nose about 2 inches off the ground,her head tipped to one side a little. Her face was quite swollen. Later in the day,she was so swollen she could barely open her eyes and she was shiverning a little. I drove her in the barn and left her. Checked to see if she was alive yesterday morning before I called the vet and the swelling was pretty much gone. I called anyway. By the time the vet got here about 3:30,all the swelling was gone and she looked normal. She checked her all over,there was no odd smell,no sign of infection,no abcess,nothing. I turned her out and she's still fine this morning. I've just got the feeling that if I hadn't caught her and called the vet,I'd have found her dead.
