Investigation Time
When you go out for a walk, there will come a time when your dog halts all of a sudden and raise a foot. No, they likely did not hurt themselves. They are actually figuring out whatever it was that caught their eyes. Their brains are working! Dogs also tend to sniff a lot when they are playing detective.
Straightened Tail
A tail in the air can mean excitement or confidence. Dogs often do this when they meet another dog or animal. If the tail stays up and shaky, they might feel challenged. A happy and content dog often has their tail at level with the body. A tail hanging low or tucked between the legs can mean insecurity.
