Mine loved the Omega Tricky Treat ball, Kong Wobbler, Starmark Pickle Pocket- gosh, we have so many others as well but those are the ones that come to mind first. I could put their entire meal into the tricky treat ball or Wobbler but usually gave them half in the bowl and half in the toy. They are still so happy when I put part of their meal into one of those. They also like the Orbee tuff Snoop toy although it might be large for Archie. Lark keeps trying to chew the trumpet end off the Kong Genius toy but Chase liked that one. He figured out how to tip it up so the kibble would come out the trumpet end, Lark tried to chew through the side of the toy. Maybe not a genius there! Some of them come in different sizes so you would pick the best size for Archie.
