This posable plastic dog is so cute!!  He is approx. 2.75" tall and 2" long. The ears are silicone.

He has a LED bulb.  You need 3 button batteries for him to work.  They are LR41 batteries and 3 extras are included.  I suggest having someone with small fingers to add the 3 batteries.  To buy them is super cheap.  I added batteries to one to check out how bright it was and nearly blinded myself as it's an LED light. 

I'll go ahead and add batteries so he'll be working when you receive.
