Can dogs blush?

Len took the team for a run today, in preparation for a local race tomorrow.

'Cookie' managed to bite the tip of her tongue while running, which we noticed upon Len's return. It's a common thing that happens. Her tongue had slapped the sides of her cheeks, and created this 'blush' on her face. She was the only female in a team of 8, which makes it kind of cute. Her tongue is perfectly fine, not to worry.
