There were two types, one semi-large and huggable, and another much smaller, that could fit in your hand.
The price for the larger was around $16, while the smaller were around $8. Also, the smaller ones had a voice-box, so you could pinch their wittle ears and hear them bark; cute. Also, they had Nintendogs written all over them, literally; on their collars and branded on their arses. Interesting to say the least.
