Don't purchase
I bought this off of a different site, there were fake reviews on the site I got this product from.  So many red flags; no instructions, no paperwork for the guarantee the site promised, couldn't find where to put batteries for the longest time, once new batteries were put in....it stoped.  Any movement was minimal for a golden retriever to be enticed by.  He was curious for a short moment with just watching it move small movements and then it stoped.  Spend your money on a different toy for your pup(s).
