Yawning
This one might seem like an obvious indicator of tiredness, but that’s not the only thing a yawn can indicate. It can also mean that a dog is nervous or stressed, for example when they are at the vet. Yawning can also indicate security and submission in a dog.
Wriggling Around
It’s always adorably hilarious when a dog will begin wiggling around and kicking their legs in the air. This could just be their way of trying to scratch an itch, but it could also be their silly and cute way of grabbing your attention.
