Repairing fur is best done by a professional furrier, but this can be costly when if you have an inexpensive vintage piece that isn’t worth spending money on. If the leather of an inexpensive fur coat begins to crack or tear, then there is a way of repairing it temporarily, and on the cheap. Get a piece of leather and patch the tear (on the leather side of the fur, of course) by gluing the piece of leather over the tear or crack. Use a leather glue or a latex-based rubber cement, like Copydex, this will keep the leather soft and supple, and will help prevent it from tearing any further.
