Licking Themselves Clean
It is no secret that dogs can lick themselves clean. They will try to do this if they are dirty, but it can also mean that they are hurt. A dog licking their legs and paws a lot, especially near the joints, should be brought to the vet. Better safe than sorry!
Snarling And Showing Teeth
Dogs also show their moods in different ways. They are not positive all the time. If a dog wrinkles their muzzle, it means aggression. If they are snarling and showing their teeth, remove them from whatever situation they are in. This means they are ready to attack any time.
