The reason why dogs have erect ears is because the genes of some breeds have erect ears. Dog breeds such as our common German Shepherds and Shiba Inu have erect ears, which is better for them to collect sounds, and dogs with erect ears Dog ear canals are usually relatively clean, but for dogs with unerected ears, we need to check their ear canals frequently.

Tip:

Dogs with erect ears are not born with erect ears. They need to grow for a period of time before their ears erect. Different breeds have different ears erect time.
