Shoulder joint: The flexible ball-and-socket joint formed by the junction of the humerus and the scapula. This joint is cushioned by cartilage that covers the face of the glenoid socket and head of the humerus. The joint is stabilized by a ring of fibrous cartilage (the labrum) around the glenoid socket.
Dogs can drop/lower their ears when they are both happy and nervous. Itâs important to read the rest of the dog. I prefer to call ears, âdroppedâ when the dog is offering pro social behavior, like our dog below. You can see our dog is offering a lovely kiss to his friendâs face. His body is likely wiggly and loose.eutral position means that they are not pricked forward, drooping down or pasted to his head. Whatever the dogâs breed, they are just sitting easy. Here is a relaxed dog with neutral ears. The other body language that tells me this dog is relaxed is the big open mouth and relaxed, drooping tongue.
That's why they don't vary as much in size as dogs do. They are also mainly nocturnal animals so it is advantageous for them to have upright ears on the tops of their heads. They can move each ear independently to pick up sounds, Cats rely on their hearing more than dogs do but both animals have good hearing.he reason dogs have different shaped ears is due to their breeding. Most dogs were bred to do specific jobs. Some of those jobs were better suited to dogs that had sloping ears while others were fine for those with upright ears. People need to remember that all dogs were bred from wolves, which do have upright ears.
