- Reading Dog Body Language
Tail The higher the tail, especially the base of the tail (where it meets the dog's body), the more excited the dog is. Don't confuse "excited" with friendly. A friendly tail is wagging big wags and the base of the tail is about even with the dog's spine. A wide, low wag or a happy circular wag are both excellent signs of social intent. A stiff tail held straight up nearly vibrating (short, quick movement) is an excellent sign of scary intent. So is a raised stiff motionless tail. Watch out!
Alignment What is "alignment"? Think straight like an "arrow". The straighter the dog's path of travel toward you is, the stiffer they are, the more arrow-like they appear may signal more risk. A friendly dog is "soft" and wiggles when they wag; a tense dog is not and does not. An arrow-like dog may lie down as you approach. That is not a friendly posture. Think "lion hunting" and you'll be closer to the truth most times.
