Why are a dog's ears red inside, the reasons? - in detail
The reddish hue of a dog's inner ear is a unique characteristic that can be attributed to several factors. One primary reason is the presence of blood vessels near the surface of the ear canal. These vessels are highly vascularized and close to the skin, which gives the inner ear its distinctive red coloration. Additionally, the skin of the ear canal contains numerous capillaries that contribute to this appearance. Another factor contributing to the redness is the presence of ceruminous glands, which secrete a waxy substance called cerumen. These glands are also highly vascularized, further enhancing the reddish tone. The inner ear's environment is warm and moist, which promotes blood flow and maintains the coloration. Understanding these aspects provides insight into the complex physiology of canine ears and their unique characteristics.
