I have a 12 yr old cow. When this cow walks, her back feet walk in a straight line instead of seperated. When she eats, hay, feed, her back feet move constantly back and forth, sideways. When she is laying down i have to get her up to let the calf nurse and when she does she stays with her back end up and her front end down for about 5 min. then she gets up the rest of the way. I want to keep her till the calf is weaned, he is 2 months old. I am really worried she is gonna die on me, and i am afraid her days are numbered. If anyone has heard of this and has some help to ease her pain till i get wean the calf.
