My dog is obsessed when she smells them! She has torn the table cloth off the table, dug at my jacket until she retrieved the bone in the pocket, will not settle until she gets the bone when she smells them! Once she gets the bone, she is fine. It is absurd, like dog catnip... I thought it was to CALM the dog, not cause them anxiety? She has never never acted like this for any type of treat in her 9 yrs of life!
