I have had, rescued, and taken care of a wide variety of dogs from smaller malti-poos to a Dane who had been living on the street, was skin and bones, and ended up 188 lbs. Currently I have Pippa, a 7-year-old Labrador who is allergic to chicken, so I make part of her food. I am home most of the time, except when I host overly-complex board games at the Hickory Library or the Highland Rec Center -- and those sessions are at most 3 hours long.
