Faster than a speeding bullet??? Our Yorkies!!!!
Yes the zoomies go on at our house too when you least expect it. I do take Nathan outside without a leash since we live on a private road and there is nothing around us and its too far for him to get to the main road!!!
He is usually good when i call him if i feel he is going to far..although i do have to call him more than once and use a little stern voice to get him to move!!
