The VTech 1,2,3 Walk Me Puppy is a wiggle puppy designed for children ages 12 to 36 months. When pulled by the rope leash, the puppy moves with a wobble, singing encouraging phrases and songs. The letter and music buttons trigger the alphabet song, letters, first words and phrases on the puppy. The toy helps strengthen fingers by rotating the puppy's tail and stimulates tactile senses by patting its head to see its ears move. The toy requires 2 AAA batteries, included for demonstration purposes only, and new batteries are recommended for regular use.
