Barking Can Mean Different Things
A dog’s bark can mean numerous things depending on the situation, how they bark, and what they’re barking at. if a dog is barking particularly loudly and rapidly, they may be showing aggression or could be sensing danger and are trying to alert you.
If a dog is doing short and soft barks it can mean that they wants to play and are excited. However, if you hear a dog yelp loudly, it most likely means that they’re in pain.
Beware of a dog that wrinkles its muzzle.
