Why do Pharaoh Hounds blush?
Pharaoh Hounds have a unique trait where their skin can appear to “blush” or become slightly flushed, especially on their ears and faces. This is due to their thin skin and the lack of an undercoat, which makes the blood vessels more visible. When they are excited, nervous, or even just after a good workout, you might notice this temporary change in their skin color.
This blushing effect is a distinctive characteristic of the breed and is often considered one of their charming features. It’s not related to health issues but rather to the breed’s natural physiology.
