I suggessted that to my sister, she is also going to get a kong toy.

I myself will look into a local dog training class even if it takes her mind of things for an hour, she is stubborn as a mule lol
she is soooo active 24/7, even my daughter, myself and her bf have took her out for hours and i do mean for hours, after that she go's back indoors, has a drink, sits down for half hour and is on the go again for hoursss lol.
i truly in my life havent met a more active dog as flo, she is beyond a joke, we truly donot know where all this energy comes from. nothing works.
