Brought dog for hyperactivity issue and dr. gave her a senior wellness screening and shes only 5 yrs.old. wanted us to buy a behavioral collar and drops for food. Short on cash so asked for just drops and she recommended the collar if i was to choose one. Collar not working and it says on the back of the box "not for hypoactivity issues. $45.00 wasted. Online only would have costed $13.00.
