I have the original (ERS-111) that I bought used - even for as old as primitive it now is, it was remarkably fun for its time and offered entertainment without the complications of an actual dog (vet visits, pet deposits, etc.) Now it sits since the battery pack has died again and I don't want to deal with replacing it but I do miss it.
