The Xolo ear usually needs temporary support to grow erect as the puppy grows. Many different parts of the puppy’s body are competing for the available nutrients and calcium that make the ears stand erect. When the adult teeth come in and have formed, then there is more available calcium for the ears and they generally are erect by 6 months of age, if not before. We usually begin taping the ears at 3 weeks of age, very early, so that the pups learn to tolerate the slight discomfort involved. Here we have photos of 4 week old puppies that have their ears taped and another photo showing how they look when the tape is removed after two days.
