My dog was recently bitten by a stray. As she jumped back, the incisors or canines from the other dog sheared the top of her ear down a straight line out. It's now stitched up, but the outer 1/4 inch portion apparently has no blood supply or vascularization, so I doubt it will ever regenerate back together. Any suggestions? According to Wiki: "Outer ear trauma: The auricle can be easily damaged because it is skin-covered cartilage, with only a thin padding of connective tissue (the auricular cartilage). That entire cartilage framework is fed by a thin covering membrane called the perichondrium (meaning literally: around the cartilage).... If portions of the cartilage starve and die, the ear never heals back into its normal shape." The situation is even worse in canines because they have much thinner ears.
