15. Sniffs around forever before urinating. To a human, urination is urination. To a dog, it’s an elimination process and a way of communicating. So a dog has to take in the various olfactory notices left by other dogs before leaving a message of his own. He may even want to make sure that no other pup has previously urinated in the spot he’s considering. An “all-clear” sign takes some time. Be patient. He’s not trying to drive you crazy.
16. Sniffs other dogs’ behinds. If smelling were seeing, humans would be considered legally blind by those in the canine world. Dogs would feel more’s the pity for us for not getting anything out of sniffing the behinds of others. Pheromones generated from the glands around a dog’s anus let another dog know the identity of another dog. They’re as crucial to learning about another dog as the pheromones contained in vaginal secretions and urine.
17. Pants. Unlike humans, dogs don’t have sweat glands on most of their skin. There are only a few on their paws and around the anus. Thus, they don’t have the mechanism we do for cooling their bodies by losing body heat through the evaporation of sweat. Rather, the way they regulate body temperature when it starts to rise is by panting. The faster a dog pants, the more water-saturated air he is breathing out (evaporating) from his lungs, and that has a cooling effect. That said, dogs don’t pant only when they’re hot. Sometimes they pant when they’re anxious. For instance, you might see a dog panting when he’s suffering from separation anxiety or thunderstorm phobia. He’ll pant, pace and generally look nervous.
18. Acts happier around dogs of his own breed. It is believed that dogs do not have a sense of self-image and do not even necessarily recognize themselves in a mirror, so it’s not vanity that is attracting your pet to others of his kind. It may simply be that your pup had good experiences with his siblings, so he seeks out others who look like them. It can work the other way, too. If, say, your pet is a Border Collie who has had unfortunate experiences with Cocker Spaniels, he may spend his whole life acting aggressive or fearful about that breed.
19. Lays his head and front paws splayed out close to the ground while sticking his rump in the air. That’s what’s known as the play bow. It’s a dog’s way of saying that he wants to play—or keep on playing. When a dog does that, he’s in a very good mood. All dogs (and coyotes and wolves) are genetically hard-wired for this position. When another dog sees it, he knows that the lowered head is an invitation to come forward, while the rump in the air is a signal of playful, frisky readiness. Oftentimes the lips of a dog doing the play bow will be retracted in a kind of teeth-showing grin. The oncoming dog will make note of that signal of friendliness, too.
20. Chases his own tail. Is your dog a Bull Terrier or German Shepherd? Those are the breeds most likely to go after their own tails. But it is not normal doggie behavior, for them or any other breed. It is believed that tail-chasing starts in dogs with a high predatory drive with no natural outlets for their predatory instinct. One day, out of boredom, the dog spies his tail from the corner of his eye and tries to pounce on it. The result is that circular tail-chasing motion, which is perfect, in a way, because the tail moves away just as fast as the dog moves to catch it.
Unfortunately, for some dogs, the behavior becomes so ingrained that they do actually get hold of and bite their tails, causing bleeding. Other dogs spin themselves into extreme dizziness for hours on end, barely even taking time to eat or sleep. That means the anxiety arising from the inability to stake out real prey has resulted in a compulsive behavior that can only be corrected with a major lifestyle change (allowing the dog a lot more free rein in the woods, for instance) or anti-obsessional drugs.
