Why does your miniature schnauzer walk in circles?
Our miniature schnauzer used to walk in circles (on the leash) and this later turned out to by a symptom of blindness. A quick way to determine whether your schnauzer is blind is something called the "menace test." Crinkle up some newspaper into a ball and thoss it lightly directly at your dog's face. If he does not react to it before he is struck, then he may be visually impaired. PLEASE, never throw anything at your dog that might cause him injury. Use only a small amount of newspaper that will not harm the dog. There is an alternative answer to this question and that is if a dog wants to get away and is teathered on a leash, the only way for him to continue running non-stop is to "orbit" around the dog walker.
Dogs also lick because they like the taste of an owner's salty skin and out of habit.
Mostly, with domestic Dogs, it's a sign of affection.
Licking releases pleasurable endorphins which gives Dogs a feeling of comfort and pleasure — like the feeling people get when they are biting their nails — it relieves stress.
