If you want the dog's ears to stand upright, you need to make a special construction on its ears that will support the ears in an upright position. The design must be worn until the dog is 6-8 months old, because of the possibility of falling ears when changing teeth. When you have made a contruction, it can be worn for up to 7 days (if it does not bother the puppy), after removing the construction, the ears must be cleaned, checked for irritation and given a rest for 1-2 days. After that, you need to make a new construction.
Below you will find two videos in which I will tell you how make and remove the construction in the most comfortable way for the dog.
