Everlasting treat

The bad news is that the treat is not everlasting (my dog ate it in minutes). The good news is the shape of the holder can work for any kind of treat or kibble! My dog has gotten countless hours of stimulation out of this over the past 4 years! I make it harder for her by covering the treat openings with fabric or something from the inside. Also, she is a heavy chewer and she hasn’t damaged the toy itself
