Please choose the correct ending to complete the given sentence: Uncategorized: [header] How to understand what your dog wants [title] Watch him move.

Ending1: He's hoping to communicate with you, not walk in straight lines. [title] Notice if your dog tires of walking. Ending2: As you get close, he will try to back away, shifting his weight into one leg. [substeps] If you look up at him when he walks, he has no idea what you're doing. Ending3: If he takes a zig-zagging path, you is feeling friendly. Try to read your dog's movements and respond to him accordingly. Ending4: He may do some lunging in pursuit to get you to bend over and touch the ground. If he purrs (a powerful sound), he is being suggestive of sexual desire, or just not interested in you.
