What are the characteristics of dog ears?

The biggest feature of a dog's ear is its sensitivity. They can hear things that people can't hear and can distinguish infrasound waves. But dogs love to shake their heads, sometimes scratching the outside of their ears. They are smelly and dirty, red and swollen, prone to bleeding, pus or bleeding, hearing loss and head tilt.

Therefore, it is necessary to cherish the dog's ears. First, check the dog's ears every day. The inside of healthy ears is light pink, and there is no obvious smell or strange secretion. Then check whether there are some foreign objects outside. If the dog often stays outside, especially where the grass is high or there are shrubs, weeds or lice may stick to his ears.
